Portal 2; probably, as it is based on the Steam engine, which already works in Wine. If it doesn't work, it would probably be supported soon enough. But as already mentioned, it depends on the game, and whether it requires functions that Wine does or does not have implemented. A lot of newly released simpler games work, though, and so do new games based on existing, working game engines.
