3D tvs is expected to sell 20 million next year, if you were one of those people who spent thousands on a 3D during that period you aren't going to sit around with an unseable TV waiting for major sporting events, you would buy a PS3 and play some 3D games
PS3 will probably sell 20-40 million units on the back of 3D tv sales
Of Course That's Just My Opinion, I Could Be Wrong
