Should I Buy Crysis 2 or wait for Brink?

I'm planning not to buy any more games until Battlefield 3 comes out but i want to buy one more game to play while i wait .Should i buy Crysis 2 or wait until Brink comes out. Both games look really awesome and i don't know what to get. Which game do you think looks more worth buying, and do people still play Crysis 2 on ps3?. thanks.
