I don't know. If anything, now is probably the best time to go to investors and convince them of trying something new. The $15-a-month subscription method has basically died. To my knowledge, there hasn't been an MMO since WoW has released that has been able to subsist entirely on subscriptions, most having moved to some F2P model, while retaining subscriptions as a "premium." MMOs just seem to be needlessly flailing between these two models when there are many other options that have yet to be tried.
