Pretty sure it will have
HOTAS support as they've put out videos of them using a
Saitek X-55 Rhino
HOTAS. Either way, pretty much any current
HOTAS has software that will let you program them how you see fit. I have several games that don't support
HOTAS (or even joysticks) out-of-the-box; but I can get it to work just fine with a little tweaking in the software.
IMO it's a non-issue
