During WWDC in San Francisco Apple announced that it is working on supporting physical controllers in iOS 7.

There going to be at least 3 version of it: 2 form-fitting ones and one standalone. Like this.

Such devices are already in use on Android working via bluetooth for smartphones and tablets.

Or even this.

We are definitely considering going for them (physical controllers) in World of Tanks Blitz, since it can really improve gaming experience a lot, giving the necessary precision especially for core gamers.

Any thoughts on this?
