I'm told that pro shift will also do downshifts, as per the new RT.
However, from BMW dealer:
"BMW have confirmed that the pro-shifter is not yet planned to be available for the new GSA and is not standard on the machine.
As with all these things it could potentially become available in the future."
I don't see why it wouldn't work on the GSA, if it works on the GS.
However, the big lardy GSA is the last bike you'd need a quick shifter on.
