I pre-ordered mine on July 22 at my local official Fui retailer (in France), when the fuji rep came for the X-T2 preview.
I've had a 100€ discount on the power grip because I re-ordered both ( no lens).
I've tried it for approx 1h and coming from the x-e2, the X-T2 is a HUGE improvement, no hesitation
I remember the fuji guy confirmed the deal, but I think it depend on the retailer, the type of contract they have with fuji.
I am surprised to not see such a deal for everyone. It should be available on September 9th (maybe 8th), if there is no change of plans.
