Chain suck makes sense...I was struggling to rationalize what happened in my head. I still think that the derailleur hanger should have been the weak point and not the drop out. If the dropout had not broken then i would have a repair option for the carbon stay...Sorry to hear about the issues you are going through but you did break the derailleur hanger - as Dan has explained during your acceleration something happened (from the sound of it chain suck) and the hanger failed causing havoc on the rest of the drive-train.
I would not call this a issue with the G1 Speed Concept - but more or less a accident that can happen to any bike. The only thing that matters is you are not seriously hurt.
