I found this quote rather interesting, especially as it relates to AH. In fact, an MMO basically needs to be either free-to-play or a one-time purchase with a cash shop. There’s simply not room for a subscription model these days

Depends on the market. As I posted in response to the same kind of claim on Blizzard's forums, if the game (AH or WoW) go free to play I will cancel my account and uninstall the game from my computer. Obviously some companies can make the subscription model work, at least for the time being, and I much prefer to pay a fixed $14.95/month and get full access than to have a heavily limited and poorly supported game that I would need to pay a much larger sum per month simply to get back to the features I had when it was on a universal monthly subscription in order to support the free players.
That said, I would not be upset if the costs allowed HTC to give a two tiered system, one free with access only to a limited unit set (A6M2, B5N2, Bf109E-4, Bf110C-4b, Boston Mk III, C.202, C-47A, D3A1, F4F-4, G4M1, He111H, Hurricane Mk I, I-16, Ju87D-3, Ju88A-4, Ki-43-II, LVT(A)2, LVT(A)4, M3, M4A3(75), M8, M16, P-39D, P-40C, Panzer IVD/F, SdKfz 251, Spitfire Mk I and T-34/76) to provide more activity in the MAs. That said, I suspect the bandwidth costs would not allow that idea to really be viable.
