It is all good now cuz it will be like nokia + intel = meego and also samsung + intel = tizen ,the only thing to worry about is Qt gonna lag behind the HTML 5 but that is a may be .
As long as Qt remains on top of everything ,meego will not be dead,Qt should be central to Tizen & Without Qt the Tizen OS is really gonna find hard time, and by the time HTML5 does become accepted/popular Tizen may well be a distant memory .
