Remember this:

Maemo chief Ari Jaaksi leaved Nokia last year going to WebOS...
A webOS chief (dont remember name) did enter Nokia.

Now many thinks nokia goes WP7.

To mee more logical step for Nokia is this two decisions:

One dish Meego and use WebOS

or

Officially port Qt to WebOS and make HP abandon theyr development framework and go Meego :-D (more open platform)

Both cases looks intresting...
