If every PS4 game was also available on PS3 (if not as pretty) would you get a PS4?

I'm prepared to stick with my PS3 for another two years at least.

I already experienced what you describe in the OP in the 7th gen with my PS3. The switch to HD wasn't enough for me to run out and buy the console at launch, I bought it one year and a half after its release when it started having a good library of games I wanted to play. I never regretted that decision, I saved about $150 on the console and I wasn't stuck waiting for games like it's always the case with brand new consoles.
