EDIT: The poll is messed up. Just read the last sentence to see what you are suppose to vote about.
Considering that the PS3 won't play PS2 games, it is possible that the PS4 won't play PS3 games even though nothing like that has been confirmed.
I was very unhappy with the PS3 not playing PS2 games, but I bought one anyways because the leap in graphics and the online features (PS store for example) made it worth it to upgrade from the PS2 to the PS3.
However, now that I already have a console (the PS3 that is) that supports good realistic graphics, already has online stuff, and can do all kinds of shit like playing video and audio files of an external hard drive (something which the PS2 could not do), I can't think of any real reason for why the PS4 should be much better then the PS3 is right now besides better graphics. There is a huge difference between the PS2 and the PS3, but I can't imagine the same being the case when it will come to the "PS3 Vs PS4" in the future. In fact, rumors like how you will need to register each PS4 game to one single console make it sound like the PS4 will have MORE limitations then the PS3. Though of course those things are just rumors.
However, there is one thing that could make me willing to do it at some point: BC with PS3 games.
If I can keep my whole PS3 games collection and play it on the PS4 and there won't be any "one game one console" limit bullshit, then I might buy a PS4 at some point. If Sony decides to pull of the same bullshit that it did with the PS3 however and decides to have no BC and then even try to re-sell PS3 games to us with an online store then the PS4 can go fuck itself as far as I am concerned. I am not going to buy a new console for hundreds of dollars if I can't play my PS3 games on it.
With the PS3 I was able to swallow not being able to play PS2 games because the gap in graphics and features between PS2 and PS3 games was so big, but the same probably won't be true this time because PS3 graphics are already extremely good.
So basically, if you won't be able to play your PS3 games on your PS4 and the PS4 won't offer any real improvements over the PS3 besides better graphics, will you still buy it?
