I hope they don't go nuts with the steampunk stuff...although I do have a mechanical elephant that I've been using as a steamtank...
Overall, I'm really hoping for as little change as possible. The mortar is undercosted and greatswords are overcosted (or should be made WS 5

). I suppose we should expect some sort of monster, though, since that seems to be a point of emphasis in 8th. I'd much rather have an "Imperial Zoo" type monster than a mechanical one, though. Steam Tank seems like enough mechanical monster as it is.
