The thing that interests me more is SE might be the first company to actually pull off going F2P then back to a subscription system, AFAIK this hasn't been attempted before. Most games that go F2P get a huge initial boost to their player base but that quickly disappears as players start hitting walls due to certain content or gear requiring micro transactions, that or the game doesn't continue to develop new content. In most cases i feel the games that go F2P die a slow lingering death if Yoshi P does this right the player base will go back to release levels but actually increase making it very successful.
