It's not only that Pro Controller that reminds Microsoft of its Xbox 360. The graphics do, too.
"I think their Pro Controller makes a lot of sense with the platform they've built," Microsoft's Phil Spencer told website Games Industry. "They are building a platform that is effectively a 360 when you think of graphical capability."
According to Spencer, Nintendo is probably going to use the Wii U's Xbox 360-esque controller to ensure a back catalogue of Xbox 360 ports.
"Now they are really making an on-ramp for the back catalog of games that are on 360," he added. "It is easy for those games to move over to the Wii U. They've moved the buttons around, and they've made a controller that feels familiar for 360 gamers, so I get why they are putting those pieces together."
If that is what Nintendo is doing, it'll be pretty smart at the start! It will also mean the Wii U can get ports of new games for Microsoft's and Sony's next consoles—though, those ports might not be on the same level graphically.
As with the Wii, let's see how the next generation progresses.
