Hmmmmmmm well, it is a rumor after all, so he may be lying or his sources may just be mistaken, but I really hope that it is equal to PS4 power for several reasons.And if the NX is close to Xone in power, the raw power jump from Wii U to NX will be very little, which makes me question if this rumor has some legitimicy at all.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
