I keep saying this, but it's all about perception. What's the killer app PS4 has that is so amazing?

Sadly, I've concluded it comes down to marketing budget. Sure, you still need great games, but it's only when 3 or 4 in a row get plastered all over billboards advertised as "on this console" do you get positive momentum.

People are now saying Nintendo has the opportunity to get themselves out of a hole with Wii U, if they can provide another couple of hits to back up the momentum generated by Mario Kart 8. Even then, it's a big if. OUYA might be able to get one hit from time to time, but without a run of them in relatively quick succession, those hits just become temporary blips on an otherwise flat sales graph (as happened with towerfall)
