Dark Souls II was officially announced at the VGAs this year.

I'm going to wait for an official video to show up, since it looks like Spike is taking them all down rather quickly. If you feel like subjecting yourself to the VGAs, though, it's at the 47 minute mark exactly..

No gameplay is shown or anything, it's just an official announcement with a pretty cool trailer. I would be shocked if it shows up on current gen hardware, personally.
