I think this would be a great feature (I could play my existing UMD games that I've already paid for) but this will never happen.

What incentive does Sony have to do this? They will see this as I way for people to play pirate copies of games. Preventing this also gives them a way of re-selling games to people who already have UMD versions.

Combine this with what looks like an awkward console to play (the buttons seem too close to the bottom) and you have something I have no interest in buying.

The sort of technology you are talking about only works from a very limited viewpoint. The picture wouldn't look right from lots of different angles so it's not suitable for a cinema (or anywhere with more than a small number of people). It's a shame though, it would be nice to have a 3D tv like that.

They are not the first chain to do it either! I know of at least one chain (Cineworld) that has 3D screens in some of there cinemas (Cardiff has two screens, it's a shame the cinema is crap overall).

I'd like to see if mesh networking could help with this - if enough machines could forward packets to and from a gateway then you might get good results in cities/towns.
