keep forgetting what its called, but the new one coming out soon from Xigmatek, which is massive and will probably be reasonably priced as well
I think it's called the Pantheon, Vortez have a review
here. Looks like a very interesting case with some slightly wonky design decisions.
EDIT: As pointed out, probably is the Elysium. See stulid's link below.

Here are a few cases I seem to recall as being due out in the near future, in no particular order:
Corsair 650D
Fractal Design Define Mini
Fractal Design Arc
Fractal Design Arc Mini
V3 Variants of the Antec range of mainstream cases (300, 900, 183 etc.)
Various cases from Enermax
Various (ugly as sin) cases from Lancool
There may be/have been some announced at CeBit that I haven't heard of. I don't think there's anything there that absolutely warrants waiting for, though YMMV.
