Today's 7 year olds grew up in a world where Xbox, Playstation, Wii, Facebook, Android and iPad are a normal part of their universe. There's nothing novel or special about them. If this generation of consoles finds its audience with this age group like the Super NES did for me when I was growing up, the Xbox One, PS4 and Wii U will be much-loved despite their strategies, flaws, cloud computing, DRM or achievements. They will just be loved if they have good games.
We're all cynics who can look back and compare now to then, exclaiming how Facebook and Apple have stolen the market. But for 7 year olds, the world is the world, and they're only getting started. I envy them for the ability to be naive about this stuff. :-)
