Here is a quote from the autocar website from Monday. Its about the Scirocco R, but its likely the Golf will follow the same guidelines...
"Volkswagen has confirmed its new Scirocco R will cost from 33,475 euro (£30,691) when it goes on sale in Germany later this year.
UK pricing has yet to be announced, but it is tipped to cost around £25,000 when it goes on-sale here due to exchange rates. Final pricing is expected to be confirmed later this month."
Hopefully that will mean the stated £28 - 28.5k price will stand here. The Roc was originally announced as £26k!
