When to buy Expression Studio

[numlock]

Isn't there updated versions of several of the programs coming out soon? If I purchase Expression Studio now, will I be able to upgrade to those new versions for free or discounted or should I wait?

I downloaded a trial of Expression Web and I really like it.

Only Expression Blend will have an updated version coming out shortly: Blend 2 (currently a preview is available for free.)
There will be a good while before a new version of the other applications in the suite (including Expression Web) is released, probably mid-next year. The upgrade usually costs around $99.
