The way Nokia is going in the latest press releases I think it is safe to say that more Maemo/Meego devices is not going to happen. It is over, the end is here.

Bada is an alternative, it is THE alternative to Android/iOS/WP, at least the only alternative with a future. Bada is one thing, it is all Samsung at the moment, but the core OS is unstoppable in the long run, just as WP is.
