I don't know i saw a lot of designer diary videos on Gamespot and on IGN and whatever i saw from the game i like it.
If it will be like any of the other Warhammer games it won't suck. All of those previous Warhammer games rocked. I still play them today. They are awesome.
I hope there will be a demo available soon so i can play the game before i buy it. But i am pretty sure i will buy it anyways.
