What will it take to buy the console that you don't have this generation?

For the PS4, just a lot of games that I'm interested in. I've got particular tastes and nothing interests me at all so far this generation, but last gen had a ton of stuff I liked so I'm holding out hope. Introducing PS3 backwards compatibility would make my purchase come waaaay sooner though. That alone would probably push my purchase into next year rather than four or five years from now.
