Personally, I think that's a lousy reason to check the game out, and is unlikely to present it in it's best light. Warhammer is one of those kinds of games where you think you're playing one thing, but in reality you're playing something else entirely. In this case, because of superficial similarities, you may think you're playing D&D but just with different rules, but after a handful of combats are under your belt, you'll find out that you're actually playing Call of Cthulhu, and your characters will likely be dead, maimed, insane, diseased or otherwise hosed because you had a D&D paradigm in mind while you played it.
Check out Warhammer on it's own merits; make sure that you're ready for the massive paradigm shift that it entails, and then go for it, and I think you'll find it a great game. If--however--you just think "it's D&D, but not really, so I can stick it to
WotC" then you'll probably be disappointed with it.
EDIT: Ah, I see the D&D/Cthulhu comparison has already been brought up. Cheers, guys! You're on top of things today, clearly!
