I think that nokia is going to do one of the following steps:

1.Nokia will give up meego and use wp7 for their hig-end/expensive smartphones. Symbian will be used for the cheap smartphones.

2.Nokia will use wp7 for a while to get financial better and then use meego for their smartphones.

3.I dont understand why they didnt chose android?
its market share is much higher than windows phone 7.
