I buy consoles for games I want to play, i'm not going to be sitting there thinking "this 8GB of DDR5 is amazing" while i trudge through generic FPS games. The Wii U had some launch titles I wanted to play and will continually add to it's library of exclusive games that I'll want to play.
I'll likely own all next gen consoles at some point because there will be exclusives I want to play too, then I will choose third party titles based on which is best. Obviously not everyone can afford to own every console, but if you're picking a single console, then no matter what you're going to be missing out on some amazing games - you just have to weigh up which console is best suited to you in terms of games.
