Nokia N900 vs. upcoming Nokia N8

First of all, is Nokia moving away from Symbian? I've heard rumors that for the high-end Nokia phones (Nseries), Maemo will be the OS. If this is true, then why is the upcoming Nokia N8 coming with Symbian^3?

Other than that, I am considering the Nokia N900. My question is, should I wait for the Nokia N8 before making my decision? Here are some advantages I see that the Nokia N8 might have over the Nokia N900:

1. Multi-touch capabilities
2. 12 megapixel camera
3. Can record videos in HD (720p)

I know I am missing some more, but I'll add them as I remember them.

One last question. Which OS do you think is superior? Symbian or Maemo?

I am going with the Nokia N900 on this one

Is the Nokia N900 successor due any time soon? If I buy a N900 now will I regret not waiting for the new version?

By the way, is it true you can't dial USSD code on the N900? I saw a video on YouTube where the phone said "Incorrect Number" or something to that effect when dialing USSD code (like when you are checking your credit).
