I called it! 
The
Expression tools will be available on MSDN . I figured this was an easy one to guess, seeing as tho the Expression suite is Microsoft's first attempt at design tools. I have to say that I'm not impressed, but I have faith that future releases will be much better. I still want to play with them more, but just haven't had much time. Nonetheless, I think their availability on MSDN will make them much more likely to be adopted. The only thing I'm wondering now is, what will the big announcement at Mix '07 be? Hmm... There are still a number of things I can think of, but my curiosity is even more piqued given this turn of events.
