Unlikely to drop Xenons in the UK - UK Buyers kind of expect that kit - agree with J400uk - Sat Nav will probably be standard soon - or mirror link which would allow some kind of Sat Nav from your phone. Just spec a new UK Passat and you will get some idea of what's next for the Golf.
It's an oddity that Sat Nav is not standard on the performance Golfs, that said UK buyers love their bling, so it probably has to make way for that.
