I know anything's possible, especially with Nokia, but when this guy, who works for Nokia, says that they are working on the MeeGo kernel for the N900 and all the drivers for the N900 hardware, there's not that much more you can expect from Nokia at this point.

So many things can still go wrong with MeeGo that a full commitment at this point is something I feel you just won't get. Knowing that a Nokia team is working on tailoring MeeGo for the N900 is the most I expect at this point and I'm happy to hear it. I was worried that they were working with N910/N1000 prototypes.
