Would you need to buy a new receiver if you want to get on the 3D bandwagon?

Basically, yes.
Even though 3D sets are just around the corner, hold your horses. Bluray's 3D specs have only just been announced, and expect them to change or be upgraded within the first few years of it's life - look how much standard Bluray has changed in the last 3 years.
That's even if you want to be bothered sitting there with welding glasses on spending a fortune on 3D Bluray discs. And all that for Mr. Average's 40" screen which he sits 4 m away from. Even though people are buzzing about 3D, I really don't think they've thought it through fully.

I'm not disuiting this, but wondered why it would be?
I'm thinking if the addition V1.4 was 3D and maybe some other bits, but not sound, could an existing amp not grab out the HDMI 1.3 sound information it needed and then just pass through the other information untouched to the 3D TV.
Or alternatively, would it be possible to split the 1.4 HDMI signal, and send one to the amp, and the other straight to the TV?
I'm thinking maybe the problem with either of these is that devices receving HDMI either check the version, or need to do some sort of required handhaking for that version?

Just been watching AVATAR in 3D the movie it self is realy great but the 3D experience watta big disappiontment it was , you have to sacrifise alot in another arial's such as contrast, brightness,colours, just to add some gimmik effect as if things are jumping from the screen right at you , which are very obvious and artificial most of the time, and not to mention the pain in your eyes and headache that many people get's...now if was 13 years old again and i had to be some gaming freaks, probably then i might be impressed 
I went to watch Avatar at the Imax and i was blown away by the film and 3D expierence i thought it was stunning! I have also seen U2 live in concert at the Imax 3D and again it was simply stunning so i for one am getting excited about the new technology.
I am due to update my system this year (TV, Amp, Speakers, Blu-Ray) so i am gonna hold back till the summer to see what 3D brings

On another note, since you do need HDMI 1.4 compatibility for 3D how is the PS3 going to handle this when it's HDMI 1.3? Sony state that the forthcoming firmware update will allow it play 3D at 1080p.

You're quite right - 3D per se is compatible with HDMI 1.3, as it has more than enough bandwidth. My understanding of the situation is (and i'm happy to be corrected if anyone knows something different) is that the frequency of the 3D signal will either be 48 Hz (i.e. 2 x 24fps) or 120 Hz (2 x 60Hz). Current receivers are usually only capable of passing through a 24Hz, 50Hz or 60Hz video signal. Which is where the problem comes in.
One way around this would be if 3D blu-ray player manufacturers bothered to make them with dual HDMI outputs - one for carrying 3D video directly to a display, and a second HDMI to carry hi-res audio to the receiver. After all, blu-ray players have optical, coaxial or analogue outs for audio, so by this rationale there is no reason why 3D blu-ray manufacturers couldn't have a second HDMI output on their players for audio purposes. Whether they have the foresight and the will to do this of course is another matter entirely!

HDMI 1.4 splitter anyone ? It should do the same job - one feed to the display, and one feed to your V1.3 AVR as the splitter should be backward compatible.
More than likely cheaper than a new AVR.

3D just gets worst and worst!
So unless you can buy a splitter (although that might cause signal deterioration) or a bluray player with two HDMI outputs, everyone who is interested in going 3D will need to replace there TV, Bluray player, Cables and now Receiver.

I know, crazy isn't it? I can handle the fact that if I want 3D i'll have to buy a new TV and blu-ray player at some stage - after all, it's new tech, new features, and the decision to upgrade is entirely mine. However, to have to upgrade my amp - not for new tech as such, but purely for a compatibility issue that the manufacturers could have found a simple work around for - is far more difficult to stomach. I know the vast majority of consumers don't have AV receivers and the like, but early adopters who do have AV receivers are important to initiate uptake in the first year or two of new technology, and this AV receiver issue isn't going to help the cause of 3D at all.

Couldn't have put it better myself.

Yeah, unless there is some kind of workaround it seems like I'll just wait a few yrs before I take it up.
Have to agree with FrankHarveyHiFi. The thought of wearing giant novelty glasses on top of my regular specs every time I want to watch something just annoys me! And thats after spending another couple grand on a fancy 3D tv, a few hundred on a new 3D bluray player, more again on a new 3D amp and then probably a couple hundred on 3D cables! And no doubt if you're an "early adopter" of all this 3D malarky you will need to upgrade again in a few years!
Actually, I take some of it back - the upcoming Panasonic 3D blu-ray player does have 2 HDMI outputs, because of the receiver issue. Good play to them, a company that is clearly thinking several steps ahead! There is a video confirming this
NO, THERE ISN'T A VIDEO, as it contravenes House Rules. Please refamiliarise yourself with them - MODS

Comforted to know there is an HDMI splitter that covers off these kinds of situations though.
I'd have hated to have thought I couldn't take advantage of newer pieces of equipment with later HDMI compatibility without upgrading my other cmponents to the same HDMI version.
