I really feel the importance of backwards compatability is overstated. Maybe it's a result of me not buying into the next gen before I'm fully done with last gen, so when I get my new console, I only play the new games on it. There are some games I go back to, but I'm okay with using my PS3 for those. After all, that's why I bought my PS3; to play PS3 games. When I buy my PS4, I won't be buying it to play PS3 games, I'll be buying it to play PS4 games. And I equate PS2 Classics to the Nintendo Virtual Console. It's not meant as backwards compatability, and no ones forcing you to buy them again if you own the PS2 discs.
TL;DR to me, no backwards compatability is barely a mild nuisance (honestly, not even that), and I'm pretty sure most people think the same way (hence why the PS4 has sold approx. twice as much as its closest competitor). For the few people that really want to play their PS2 games on their PS4, yes, I can understand that it might be annoying, but how many people are in that situation? As for PS3 games, it simply won't happen because it's too hard to emulate. The PS3's CPU is (substantially) more powerful than the PS4's, and the architecture is too exotic for the PS4 to be able to emulate it. Be realistic.
Wow, my TL DR was just as long as my original post lmao
