We need to wait the Enhanced Edition then we can hope for a Linux version, not before imo.
Btw, rly good work on W2 Linux version. Works fine, ultra (-vsync & -ubber sampling), GTX 660M OC (1173Mhz graphic clock, 5732 Mhz memory transfer rate). Sometimes appear a little fps falldown in cinematics but in game it's fully smooth.
Unfortunately, no Full Combat Rebalance mod which I've heard makes the game really good.
