Well i've spent a considerable amount of time over the past week with a pair of 3D specs on, assessing the various offerings from Panasonic, Sony, Samsung et al.
As mentioned before, I have been a 3D cynic previously - both due to the largely novelty/kid-focused nature of the content, plus the fact that the stuff typically gave me a headache in seconds.
However, I have now seen some content - and experienced headache-free demos from the new, active shutter glasses - that is making me appreciate the great potential of 3D.
For me, the turning point was watching sport in 3D, which I found very compelling. No gimmicks, just more involving viewing.
From what I saw at the show, many of the manufacturers are making 3D a feature of their higher-end TVs and Blu-ray players almost as a default - so you're getting the best 2D quality then the option of 3D as/when you need it. If that can be achieved without a massive price premium - and broadcasters such as Sky provide tempting/relevant content - then it could be a flyer.
As we always stress, you should try things yourself. But retailers are going to HAVE to get really good demo-facilities up and running for this - with real content to demo - and that's going to be a big challenge.
