Yes everything is supposed to carry over to next gen, all current gen titles and also the whole BC library.
Hopefully when the new console is released they will start adding more BC titles but it's possible they might end up going the way Sony and ninty have (porting stuff and labelling them remasters regardless of how much or little work has been done).
I'm hoping Mafia 1 is going to be good though. The whole game was apparently rebuilt which is why I call it a remake.
