@Gyrene: I believe the P-80 saw six units arrive in Italy a week or two prior to V-E Day- no combat, hardly valid as "squadron strength." The F8F was in production prior to VJ day but was still in the process of being delivered to operational units. Neither of these examples are in HTC's criteria ballpark. (As I remember it from a few yrs back: "Must have been in general production and seen combat" but, like Krusty, couldn't find it.)
As for the rest of the examples, I'm a fan of the P-61 but don't see any of the other examples finding any niche in the MA which brings me to the next point; MW rides invariably had a bigger impact on the war than the F7F and would be great to see. There is no doubt in my mind that additions of the Whirlwind, Swordfish, Gladiator, Mig-1 etc etc. would make AH a richer historical experience. Here's my angle though: unless you are flying in EW or MW, these aircraft are not competitive. For better or worse, 95% of the AH player experience takes place in LW. E/MW aircraft will in all likelihood be non-factors (P39D graphs Lusche?) except to a very very small portion of an already dwindling player population. The F7F might actually qualify AND add to the fun factor for a majority of players. AH is the last of its breed because OUR BREED is dying. I'm not in favor of turning this into an Xbox arcade experience, that would violate what this is imho, the highest fidelity WWII sim (a digital "ark" if you will) on the market. Let's keep it interesting.
