Excellent, if I had a Mac I'd be excited right about now...sadly...I don't...

Nor can I afford ZBrush 3 at the moment, so you have a sad, sad Seppuku (That could be a ballad...sings: "he was a sad, sad, Seppuku. Cy, cy, cycling on his sad, sad, cycle, singing, asinging all day long.")
But Zbrush 3 Mac, now I've watched the pain for a while (knowing a Mac Zbrush user) and it has been a bloody long time, so congrats to all of your waiters...I'll just laugh if they announce a Zbrush 4 for Windows next week.
You sir have the moral ambivalence of a mutated shrimp!
