Nice one! I still wouldn't expect the GTi to emerge for another year though.
"...which will officially hit the assembly line in 75 weeks from today. In other words, the
Golf 8 will enter production towards the end of June 2019.
The big
announcement was made by VW during the recent “Golf 8 Supplier Summit” organized at the Volkswagen Arena at home in Wolfsburg, Germany."
I don't know if it will take a year for the GTI, but the Mk7 Golf R took a full year to arrive last time.
The Mk7.5 went into production October(?) 2016. I ordered my GTI PP the week order books opened and it arrived August 2017 = 11 months. So yes it could take a year for the UK market.
Spring/summer 2020 is still over 2 years away.
