Yeah, I'd stick around to slaughter the noobs, and spam 262s at them for about a month or two, then probably move on to WWIIOL, or Rise of Flight. Something.
However, it wouldn't be a TERRIBLE idea to offer the Panzer IV F, T-34/76, SdKfz 251, P-40C, 109E, Spit and hurricane I, F4F, C202,He 111,B-25, and G4M for free. At least for something like a 6 month trial period. If it works, and HTC doesn't lose paying subscribers, why not roll with it.
