Just to offer a dissenting opinion, I'm not really excited at all for cm9 on dx2.
I came to dx2 from a Droid 1. While Pete did some excellent work getting gingerbread running on that thing, even with a proper kernel it never felt as good as it did in froyo.
Seeing some of the problems he's having in this alpha, including data that just flat out doesn't work, and will require an extra layer of translation for it to work, I think I'd rather stick with CM7 until I can upgrade to something ICS native.
