I don't intend to get a PS3. I don't think I've even had my PS2 for more than a couple of years. There are still many games I have left to play on it, and many games to play on my other consoles. The PS3 is expensive and I'm interested in none of the games currently available so I won't be getting one for a looong time if at all.
See, that's what Sony needs to worry about, but they seem to be completely oblivious to it. I still have my PS2 after 6 years, it's never messed up on me once. I actually AM starting to run out of games that I'm interested in playing for it though, as I've bought just about every one I want, but I have absolutely no reason to upgrade to a PS3. If they actually bothered to keep backwards compatibility in then it wouldn't be as bad.
And I still don't believe it was necessary to take backwards compatibility. They said it was necessary to remove dual-shock from the controller to have motion sensor, but guess what, it wasn't! What they should do is take out the Blue Ray, since HD seems to be winning.
Only two games I'm interested in and no backwards compatibility except on the expensive model ≠ me buying a PS3.
