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
