So some food for thought here. When Kojima was talking about Snake probably not being in Smash 4, did anybody else think he was only talking about SOLID Snake? We always have Big Boss because of Phantom Pain.
Not to mention, supposedly somebody hacked the Wii U when it first released and found that there was a MGS title being worked on for Wii U. Take that into account, and we could see at least one version of Snake back in Smash. @
Johnknight1 has more information on that.
But yeah. My hype is real. The fact that the hashtags are #Whatfor and #Keptyouwaitinghuh make me feel as if it's not supposed to be as obvious as it comes cross. The picture itself is for the Phantom Pain, but there isn't anything in particular pointing towards the Xbox One or PS4, which is something that is basically always in pictures of anything relating to it marketing wise. This one doesn't have anything, and it's talking about the day that Snake will return...which is the same day as the Smash session, and Nintendo's day as a whole.
Take that as you will, but THE HYPE TRAIN CAME EARLY.
