My opinion:

The future looks mighty bleek.

At this point in time, we are on a life supply of open pandora, qt, nitdroid, ubunto project and a falling community.

The n900 depends on the open pandora community for help with the emulators, if their emulators get an update, expect an n900 update as well, provided that some developers remain and port code.

As for QT, Nokia is planning to use meego to push qt in the longrun...so meh

Nitdroid and ubunto is a Work in progress, who knows how dedicated the project developers are seeing a dying community. And as for the community, we were at one point reaching a "peak" but as any one can see, we are all but declining.
