New iPad, which games should i buy?

Depends what you like:

Temple Jump is a fun and free game, angry birds is fun, plants vs zombies

If you like rpgs: Ash 1/2 Zenonia 1-4 etc

If you like sports Baseball superstars 11(12 is a disgrace and got rid of core features)

And this is why the other forum should never been deleted a big recommendation thread was gone with it

Now some of those may not be on the ipad(I have ipod touch) but most should be

Buy Killer Whales! Super fun!

These aren't all released in 2012, but

Beat Hazard Ultra is a fun twin-stick shooter. I think it's free or that may have been a promo.

Chaos Rings is a great RPG. The sequel was just announced for Japan.

Final Fantasy III is a bit pricey, but it's my favorite RPG on the system.

Peggle is like the best puzzle game ever made.

Espgaluda II is one of the best shmups I've ever played.

Jetpack Joyride on the other hand is the best game I've played on iOS. It's free. Get it now.
