After Virpil finishes the AH-64 collective grip the next thing they could improve upon is the CM3 throttle, or their pedals in some way. They just recently updated both of their flight stick bases to new adjustable ones so unlikely to see yet another base from them anytime soon. Collectives in general are already very new from Vipril so an updated one of those is also unlikely. Their pedals and throttle have been around for a while though, and they already recently added a new control panel to go with the collective.
Unless they want to make cyclic grips or something.
Winwing is more likely simply because they currently have a reputation of surprising us simmers with what they have in store. The F18 front panels for example, the force sensing base, and the F16 grip/throttle plus the new throttle to replace the old one have all exceeded expectations again and again.
