Possibly it's the originally plan device, but since they delayed it so long, the device is way outdated, so they come up with a new device? I don't know, but the MeeGo Harmattan was pretty old news, and this thread started since last year. Now, it's almost a year since this thread started.... By the time this phone is launched, it could probably be end of the year? In Malaysia, probably in Feb/Mar 2012? Just my baseless speculations.
IMO, they need to launch it fast, by the end of this year, who knows what other device is in the market or announced, next year, I think more, and this device will look even more dated by then. There might also be a real actual MeeGo device?

They might need to capture the market and attention, and make sure this doesn't disappoints, else, the it will tarnish the image of future MeeGo devices.
