One of the chaps on the other forum seems to have some more info:
"For 2017 BMW is only changing colours for GSAW. Tripple black coming your way. No added bhp for now.
For the normal GSW they are going to slightly change the direction.
There will be 2 models available in GS with an emphasis on one for road (Straße) and and one for more off road (Gelande) version.
The Street version will be more sporty (S) with the S in GS in red. It will come with cast/alloy wheels and slightly higher bhp and more street orientated tyres. (Maybe went back to lighter flywheel and had stalling issues sorted?) Enduro Pro will not be available but as an improved "sport" setting. It also loses the hand guards.
The Off road version (G) will have spoke wheels and will include crash bars (lower only), wider footpegs, off road brake lever and pannier racks like GSA and an option for off road tyres. Also will have slightly more suspension travel (equal to GSA) and 21" (option) front (same as offered by Wunderlich). This version was as a result of the GS Trophy event where they took the standard GS and pimped it up a bit and a lot of GS riders preferring this over a full fat GSA.
2018 GSA models rumour has it will then be updated with a form of hill start assist."
