Not sure about it.
Not really impressed with the design differences either. It is typical VW - evolution and not revolution 
The GTI MkV is a great car. No wait, it's a fantastic car. They don't need to go back to the drawing board IMO. It just needs a few tweaks and adjustments, maybe refine the interior some more, give it more grunt and stuff and hey presto, a fine successor to the MkV.
I think the MkVI pics that have been released are stunning. The car looks really, really good and I can only imagine how the GTI may look. Think positive people!!!
