If you are interested in 40k games i found this an interesting read: http://uk.pc.ign.com/articles/108/1080371p1.html
Everything I have heard about this puts it in good stead, one point i'd like to make is that the factions as far as i heard leave the potential for expansions very open, Tau can set up an expeditionary fleet, Dark eldar could raid from somewhere outside the original games system, Necrons could appear on isolated planets after the nids have finished with them. In fact i think the idea of using Tyranids as the pve race is ingenious, the only race that could adapt to pretty much any type of planet, and they don't really suit the idea of a human player anyway.
Plus it means players get to try and fight carnifexes...WIN!
