Actually, I'm more excited about this new feature set than the last one. V7 really was a 6.2 release. V8 may not be "full release" material, but it certainly does have some very useful improvements, at least for me, including:
Video Colour Palettes: This will be truly useful for me, as I hate having to save to Quicktime format, just to get colours to stay the same for Video :|
Nested Layer Sets: While I don't use layer sets nearly as much as I should (the more I design, the less layers I use nowadays), I can see this being truly useful.
Filter Layers: FINALLY! This was the most requested feature for v5-7, and Adobe finally pulled it off! This is one I'm very excited about, way more than the silly Heal Tool
Non-square pixels... Finally, I can't wait to see how this turns out, as it really would be a very different world
All in all, I'll still be waiting for more evaluations, but I'll definitely look at purchasing 8 (I didn't upgrade to v7, though we did at work)
I have 7 and its a dream being more vector based than 5. This one seems to have a lot of new vector tools like text to path. That will be a new awesome feature. Filter Layers will be really nice. Video Colors will also very useful to me. Overall I can't wait. I wonder what Illustrator is going to fee like!
