sjgadsby is correct. N900 was associated with Maemo 5 and there were expressly no guarantees that it would support the successor to Maemo 5. Maemo 5 was always the penultimate step in getting to the real crowd-worthy Maemo. Yes, things changed in that now Nokia is heading onto the MeeGo track. But all along, the N900 was still part of a sort of long-term beta program that began with the 770. The next step in the Maemo evolution was the one that was to have real longevity. (Which is one reason why I stayed with the N8x0 series.)
