I give it 2 years before we see another iteration of this tired and overdone series.
Fuck you Sempai you stupid fuck. Read what they actually said... "bringing the [...] Tiberium series to an epic conclusion". The keyword here is Tiberium series. Of course, they are not going to stop making C&C games. They are only going to stop making PC-exclusive C&C games within the context of the Tiberium series or universe. But you bet your ass that they have very detailed plans to bring the next C&C generation to consoles and probably not just stratgey games but also new console-centric action games like Renegade and stuff like that.
PC-exclusive C&C in the Tiberium universe is over though. They're not lying about that at all.
