Even if I never expected it, I agree with Snake Eyes here. And even though I recognize his intention to smuggle Bearcat in

Sure, have it, but only after Ta 152, He 162 and Me 262 get in (by the time when it entered service). Bring Bearcat at the time of the Go 229

Now seriously, the planes we have here would be uberplanes against 1941-42 planes. But between themselves they are fairly close. 1945 planes would be slightly uber to the ones now, but again, not between themselves.
So, let HTC finish what it has started. Continue to follow the plane development until mid 1945, or even later. Finish the timeline with late war what-if planes and what-if scenarios, and then develop the planeset from early war. Spain would be nice indeed.
Ta 152, for example, has such an incredible charisma among Luftwaffe types. Not to disregard it from marketing aspects. I guess we all agree that AH would not be so popular if it started with 1940 period, with no F4U or P 51. Ta 152 would attract new players - even the loud ones who shout 'dweeb mobile' would come to try it out.
For once, do not listen to elitism crowd, calling everything produced after 1943 a dweeb plane.
