I don't know about devs waiting, etc. There is a quite a few interesting community projects going on. personally I'm currently trying to decide what to do as my next project. It's a big decision for me because I don't want to write applications that doesn't interest me for free. For example from your list games are the only one that I have interest in. For the others I have no interest or there's already good enough solution available for me. Maybe I should write some kind of logic / puzzle game.

What commercial devs are doing or are they waiting? your guess is as good as mine. We'll see after ovi store opens for Maemo.
