A wait measured in years really is unacceptable and will discourage many skinners from submitting work, giving the subpar skins even more inertia to remain in game. I'm sure HTC didn't intend for it to turn out this way.
I would really like to see HTC introduce 3 more '51 models - the 51A, the coffin-canopy '51B, and the early '51D without the tail fillet. All the other popular planes - 109, 190, Spit, '47, F4U - have multiple versions and the ultra popular Mustang really seems short-changed in this area. Kind of surprising to see such outstanding work as Fester's 361st '51D LOU IV on the wrong airframe, too.
