We’ve just discovered, with the aid of TradeMork, that Sony have registered “Resistance 2” as a trademark. Although it’s not absolutely clear evidence of a sequel, it’s quite likely this is the start of something to come.
Admittedly they could just be protecting themselves from getting a rogue 12 year old developer creating his own “sequel” or it could be Sony preparing for the a new Resistance. We’ll have to wait and see.
Sony have yet to make an official announcement, and we can’t go badgering them as their all off eating Turkey with their family… Pagans.
