I didn't think that a G4 would be fast enough to scrub HD so not supporting G4's isn't a surprise.
I have a feeling in the next update they'll incorporate some missing key features from iMovie '06 into the next version. In order to make it still easy to use they may do something similar to Pages where there are two different modes (1 for iMovie '08 ease of use and 1 for iMovie '06 editing).
Personally, I think iMovie '08 is absolutely perfect for most users. They've fixed all the glaring problems I had with iMovie '06 (too complicated and time consuming) and made, what I consider to be, the most efficient and easiest way to slap some clips together in no time. That's exactly what I've always wanted and I'm really impressed that they've listened.
