New is a new model, new generation is a face-lift.
I expect the GL to be FLed only at the second half/end of 2009.
It already is getting the new Comand of the FL ML, and its new steering in the Bluetec presented some time ago. So the FL will be quite small, if it turns out to already have all the technical tweaks the ML has.
The "American" giant grille will not be applied outside of the US it seems.
