I can't see any news about this from a quick Google search so I doupt that anything will happen. There are many games, which have very small community, yet those games can still be played online. I doupt that EA/Crytek will just pull the plug and shut down the servers of Crysis games. Especially when it would only cause negatve reaction due to how young this game is.
agree with you, i also didnt found anything, i think it wont happen but, as a rumor i just wanted to make sure it doesnt happens, its still a new game, with constant players.
