A Nokia Lumia Windows Phone 8 software update providing performance enhancements for the Nokia Lumia 820 and Nokia Lumia 920 has started rolling out over the air. Delivery will continue in a phased manner over the coming weeks and is expected to be complete by the end of February. You will receive a notification on your phone when the update is available for you to download.

Any thoughts as to what it could be?

personally I'm hoping that it will provide a way to force kill hung programs. Unless it's portico for the rest of the world besides North America, if that's the case then hope you all get it soon:)
