I honestly can't see it. Sure the kids may be fast at swiping, but ... it takes milliseconds for a professional with a mouse to already have aimed and shot against the head of an enemy player.

There is a reason why pros who play with controllers never play against pros on PC in shooters. And I can easily imagine the controller pros will be much faster than swipers.

So, for just building with blocks, I can see why parents just give the kids an ipad so they don't have all the running and screaming, but it probably won't be a competitive way of playing games. I only say probably because I just can't imagine me watching someone swiping on a screen.

I'm not saying that it will be on par with PC or even console but check out this clip where you will see the touch in action to the left: https://www.youtube.com/watch?v=nf9r5S-tnu4
