Here is interview of Juha Seppä who works in Devices group's R&D unit. Article says "Juha Seppä sanoo, että perusidea on parantaa nykyisiä Series 40-, S60- ja Maemo-alustoja tuomalla Qt niihin." which means something like "Juha Seppä says, that basic idea is to improve current Series 40-, S60 and Maemo -platforms by bringing Qt to those". So it looks like something is coming to Maemo.
