Gestures on Windows Phone

I can't say I was actually expecting this for the WP8 release, but I'd really like to see MS start introducing gestures into future iterations of the OS. It's a proven input method (WebOS being the best example in the mobile space) and based on Windows 8, the company obviously believes that it's the way to go on touch UIs. It'd also be another differentiator from other mobile platforms. The Win8 left-swipe (multitasking) gesture seems particularly well suited to a smaller screen.

Besides the pocketnow article from a few weeks ago speculating about this, has anyone seen any indication that they'll go in this direction? Anyone particularly disagree?
