Windy X Windam is the Success/Ninja Studio DS fighting game that features Izuna as a character, if you've forgotten, and the site has been updated with a roster of 9 characters (looks like there's one to be revealed still) a description of the system, though much more of that will be revealed later. But because the system section is up, that means there are a couple of screens, and the sprites look really nice.
