dont think so... the only thing we can expect for n900 is the developer edition of meego... and that is real meego.. n9 will have maemo/harmattan, not meego... the only possible thing could be that N9 will be able to dual boot harmattan and stock meego, so N9 would be able to get the updates of meego (from meego.com and with stock ui) but i dont think that we will see harmattan on N9
