et oui Resistance utilisera un serveur dédié pour le jeu online!!!!!!! et comme la promis Sony ca sera gratuit. Tout est dans le blog des developpeurs du jeu

“Are you (Insomniac) paying for and running the servers for this game? If so, in five years when nobody is really playing anymore, will you shut the servers down?”

TP: Hi Devon_Vice. To answer your first question, Sony is running the servers. As far as whether or not they would get shut down if no one is playing the game – I hope we never have to face that scenario!
