^^ I agree with Fryke.
I'm glad to hear the icon view has been beefed up. I was afraid they would neglect it.
I seem to recall Apple adding a 256x256 size to the icns format. They've never used it as far as I know, but I assume they intend to upgrade their file icons at some point. That would make icon view's previews more useful. They could also make a new dedicated preview view that works basically just like the current icon view, but with all dynamic icons and at larger sizes. i.e., Cover Flow without gimmicks. (Edit: After re-reading Symphonix's last post, I guess this is possible. Excellent.)
The underlying technology of Cover Flow is great (or so it seems from what I've heard), but that doesn't make the implementation great. I think if Cover Flow actually turns out to be the best way to accomplish much, it will only prove that Apple isn't trying very hard to make efficient alternatives! (But again, as long as it's not replacing anything it's not fit to replace, I'm all for it. It's cool, and it's bound to be well-suited to
something.)
Going by what Symphonix said, though, it sounds like third-party developers will be able to access the same images Cover Flow uses, so a screamin' implementation is inevitable, even if it's not in the Finder.
