if sony really wanna see their console selling, they will have to enable mkv h.264. x.264 playing capabilities in their system.. otherwise they will stay with as many as they can in their stock.
I don't know why they don't see the big picture..
yes if you enable those playback capabilities, you are opening the door for more piracy movie. But at the same time you console will sale like hot cakes. and a lot of console sold means market for the game developers and more eyes to you hardware and more money to the sony pocket. They might be thinking that, that move will hurst their playstation video store.. but believe me, you video store will never sale a shit if nobody have the console.
