Some random Twitter handle that's probably run by interns isn't confirmation of anything.
I fully expect this to be timed exclusive, which is a terrible deal from Sony, specially when they're so close with ActiBliz now. Why can't we have a long time classic mascot be exclusive as a celebration of the brand's anniversary? No Xbox or Nintendo fan was asking for Crash to come back. This will probably sell millions, then we'll get a Crash 4 with the old gameplay and it's gonna suck because it's not made by Naughty Dog.
Hope they cared enough to also bring back CTR, otherwise they ruined the whole nostalgia trip show. Makes no sense to leave out one of the best kart racers. Good kart racers still lack in the PS4 library.
