This new model seems to correct some details that I think are overly dumb about the current GS:
-Wet clutch that's not in the middle of the bike;
-Much higher air intake;
-Something closer to a "real" frame.
BMW got my attention with this, let's see how the reliability plays out.
I'm also waiting to see the Adventure model. I'm might be interested in that. Just imagine if it comes out with a 21'' wheel...
EDIT: Forgot about the bolted on passenger pegs on the improvements list
