I would hope so. But if they don't, the Moshi is a nice product and reasonably priced. You can also go to colorware.com and get a real Apple wireless keyboard in any colour you like.
Looks like the new Mac Pro doesn't even come with a keyboard anymore (did any of the current generation? My 2008 one did), just the power cable and the computer.
I'd love to see matching keyboards though; in particular I'd love to see a full-sized wireless one. The laptop-style only wireless keyboard we have now is just no good for professional apps with tons of hot-keys, even though I love the feel of it for typing.
