@OneKillWonder_: I'll pass, rather see a new one. Sure its fun, but I've played the hell out of them and if Perfect Dark HD was any indication (also played the hell out of that) I'll just buy it, play the first mission and stop again. Been there, done that (too many times).
But any sign of Timesplitters being alive would be good by now.
I'd like a new one, but I think it should be a download-only title. Keep the price low and I believe people will flock back to the franchise. Maybe cut out the single player or just include a training mission and make the rest multiplayer then give it away. Toss in a bunch of microtransaction DLC for the plethora of characters the game is famous for. Offer a "season pass" for those who don't want to bother with the pick-and-choose route.
