As far as I am aware the 'facelift' doesn't include much more than some options becoming standard and a virtual dash
Different wheels, different colours, different lights front and rear, different body kit, new 7 speed DSG, new onboard electronics (collision avoidance etc), MIB3...
Its more than change than you imagine.
Same body shell, same engines, same running gear but quite a lot has been changed.
Given that MQB is going to be with us for at least the Mk8, this is about as much as I'd expect to see changed at this stage. Mk8 is now projected for when? Maybe 4 years from now?
