The X-H1 staggered release schedule put me off the X-H2, it's gonna be an 18th month old camera by time it comes out.
Honestly, I want a higher MP body, so this should do the trick.
The Sony 70-200 f4 seems like a super low contrast lens to my eye when looking at samples and reviews, never have been all that impressed with it judging from that, but I can see renting it to put it through its paces. The Fuji 50-140 set a fucking high bar for that class of lens, lol.
I would never use an F4 lens for any indoor work, especially if it's paid work.
