Nintendo actually has to fear to bring a new IP. Because it's much harder to establish a character, especially in videogames. look at sony trying and failing with sackboy, sly and all the others.
I think Sony knows that. All their highly praised, godlike designers grew old. they'd fall pretty hard nowadays.
maybe they could make a grumpycat game or something. the internet gives birth to hyped characters nowadays.
must-have-list for platforms i don't own yet:
WiiU: Donkey Kong
XBone: Dead Rising 3, Ryse
