I think labeling it the "future of gaming" is simply for attention. If anything, we're not talking about much more than the next iteration of consoles.

While XBox and Sony were battling over who could have the prettiest graphics, Nintendo made lots of money with the Wii's unimpressive hardware, and Apple (maybe even unintentionally) and other smartphone manufacturers came in and revolutionized the mobile gaming market with unimpressive gaming hardware.

There is a "future of gaming" for consoles and more serious gamers, and there is a "future of gaming" for more casual gamers.
