The Onkyo 608 is designed for this years new upgrade 3dtv from Sky, blu-ray and then games consoles. So if this takes you fancy then your one third there with the PS3, you will need to replace your tv, and that could be expensive, with or without the glasses.You can play a waiting game and see how the Onkyo 608 or any other new 3d amps far upto last years models, which will probably be a month or tw
r else you can pick up the 607 at a good price now before they get discontinued, maybe the Denon 1910.This really depends on wether you are planning for 3d tv soon or not because if you buy a current amp that does'nt support 3d then not only will you need a new tv or projector you may have to buy a new amp to feed it all too.So i would look at your current setup and think how long before i buy a new tv, if its this year or next then seriously consider waiting for the new arrivals.
