Just like they've always been. Android sphere now, Symbian sphere before, what's the difference?
That is a possibility. I would not count on it, but I cannot deny that it might even happen; it is possible that the upcoming devices are good. But sure I am not holding my breath. IF that happens, and IF it is possible to port SFOS to a HMD high end device I sure will try to do that. Otherwice, they will be of no use to me.
