I have no idea how fast these projects are moving, I'm not a developer. But the fact that there is so many big headliner items being worked on at once, such as multi-gpu support, seems postive. IMO, anyway.
My guess is that this isn't a sign of fast progress - it's that all the stuff they've been doing in secret for the past year is now being made public.
For so much hatred, it sure is moving right along. No surprise, things people hate usually get the Green light while things people enjoy usually gets put on the back burner. But maybe something good will come of it that benefits us all.
