All very nice ...
But in fact, a lot of the material that's going to be shown in HD (football and so on) isn't the best use of the technology. Sure, you can see depth, but it's still not entirely convincing, thanks to the 'playing card' effect.
And, while you may get two pairs of specs with your TV, if the broadcasts are - initially at least - going to be 'events' then mates will want to come round and watch with you. When the specs cost around £100 a pair, that's pretty expensive when half a dozen friends want to come and watch the match with you. The ones with 3D sets of their own can only bring them if they have the same brand.
Some of the figures quoted at Panasonic's recent event suggested 3D-capable sets would be in 40% of homes by 2015. Personally, I think that's pretty optimistic.
