Wii U - I think Nintendo will try to save grace for another year or two before they announce a new console. Smash & Zelda will do good, but probably won't match previous series numbers (like Mario Kart).First/second party games will do great critically, but meh sales-wise. Nintendo people will buy it for sure. Everyone else will move on. Legacy wise - may end up being the worst Nintendo console.
Vita - I'm thinking Sony will throw the Vita a couple more bones before they really just let it go. Maybe we'll see a Gravity Rush 2 (I hope). Japanese games, multiplats, indies will have a home with Vita. Vita fans will continue to love their console. Everyone else will wonder what a Vita is or type #lolvita. Sony will mostly likely take another shot at handhelds. They will certainly learn a lot from Vita.
