I doubt there will be any noticeable changes to the mk7 despite this media announced 'facelift'
I'm sure the new mk8 still on the MQB platform will launch end of 2017/start of 2018 with the GTI in Autumn 2018 followed by the R in early 2019.
Just my one €euro's worth
You do know there has been an Audi A3 facelift? There is also going to be a Seat Leon facelift - have a google. These cars were all launched around the same time. Though the A3 facelift is very subtle. But then again the new A3 doesn't look much different from the old A3.
I'm expecting more from VW, especially on the performance models. I think they look too similar to the standard Golfs.
If it's just going to be for 1 year - then why bother with a facelift on all these cars?
