Because, thanks to Sony and MS being boring as shit, a lot of gamers have settled into a comfort zone they're not keen on moving out of. Just look at all the people begging for a 'normal' controller. Here's the thing, though, hardware makers experimenting with gamepads has been a thing for most of the industry's existence, it's only recently that Sony decided that the dualshock was "good enough", and MS followed their lead. Because they decided to be boring like that.
Nintendo has been making new and unique controllers since the NES. Hell, the Wii U Gamepad is literally the only non-peripheral 'dualshock' setup they've made, it's literally just a dualshock with a screen in the middle. Hell, it's even pretty comfortable.
What "people ultimately want from them" is stagnation, and that's the last thing I want from Nintendo. I am utterly sick of the dualshock 'standard', and I can't wait for someone to take a sledgehammer to it, whether it be Nintendo or Valve (and Valve's crazy controller is pretty fucking awesome). You can say "if it's not broken, don't fix it", but the dualshock format is actually pretty broken in some ways, and that's not stopping people from complaining about other things from being "samey", why aren't we doing the same thing about controllers?
Sometimes...boring as shit is the best route to take. Ask many PC gamers about the keyboard n mouse. If it aint broke......
One one hand yea you want companies to take risks. But when the risks arent panning out like before, maybe its time to be more of the same, samey. This controller would have been met with much better reception if it had a button layout similar to the Vita. Hell, it looks like a new Vita.
Sony and MS are boring as shit...I dont know how to even respond to that.
