Just a small update today, the official KOFXIII blog has been updated today with two new entries.
One regarding the preview event and one about the location test.
From what i can understand they are both written by Masaaki Kukino, he is basically doing a short write up of the two events as well as thanking fans for attending, and based on the comments left during the two events they will be used towards building the final game.
In other news, i came across this K' fan made sprite whilst reading Shoryuken.com's forums.
Pretty impressive work, you can check out his website here or his Deviant Art page.
Also check out his restyling of SF characters in KOFXII style.
