Looks like the previous game voice actors are back (Geralt, Trish). That's good, because I though they were pretty good in the first game.

Combat seems to be quite different and a lot more interactive too (not sure if this is better without playing the game though). But the engine looks way better and a lot more flexible than the Aurora engine they used in the first game and if there isn't to much loading, I'm going to be quite happy.
