the new feature list looks pretty decent to me. I never upgraded to P7, but it looks like P8 may be on my hard drive. Depends a lot on upgrade pricing.

Even the new figures sound exciting. 8 of them lo and hi res. plus the 1.8gig of new content, then all the legacy stuff. Mighty tempting.

the new content library...drag items from the library right into the scene..now that's cool.

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
