I'm actually pretty excited for this bike.
The 1200 GS was top on my list for bike options and having had a KLR 650, Vstrom 650 prior, I do miss the 19" front for taking "off-road" (gravel road, which the tiger works fine but street tires get ripped up pretty bad)
Shaft Drive is going to be on my next bike.
The BMW bikes are nice but maintaining them is very $$$.
The Tiger has historically been more dirt orientated until the 1050 when it kinda stepped into a tall sport bike persona which many love but it looks to be turning into a large version of the current 800 (which is a nice bike).
Hopefully the shifting is butter smooth. I'll wait and it'll be on the top of my list or I'll buy a sport tourer and a 250cc dual sport that can actually do single track roads.
