I think that the situation is very clear , and i do not understand why everybody is so confused(propably they do not want to believe that a 3 months device is already old).N900 wil NOT be able to upgrade to meego, if there is a possibility to be able to update, Nokia will announce it with proud and will not have any reason to hide it. So it leaves this situation blur because it does not want to have negative affect to the selling of n900. That's why it does not clarify the situation and told us that most (not all) application will be compative with both maemo 5 and meego and mothing more.
