Ummm, have you read the latest WD ???
I guess you haven't read the latest White Dwarf, but it seems to me that the Tau are on the side of evil this time. At least they are grouped with Chaos and the Orks, not the Eldar and the Humans. The funny thing is that the Kroot seem to be on the side of the Empire this summer. Very strange.
So I guess my Blood Angels will feast on Tau and Ork this time around.
Anyway, the movie was kind of short, and I don't know if many people here are going to apreciate 40K flash without more explination of just what everything is. Maybe you should work on that.
