"Rather than allow those games to disappear forever, we have assembled a doughty crew to keep them operational for as long as we can."

Well, yeah, there's a chance that Treyarch could go bankrupt and totally shut down all of its servers. Nothing's guaranteed in life, So live everyday like its your last! *goes back to wasting his life*
