I just found that snk-capcom.com posted a pre-EVO 2012 interview with SNKP's Kei Yamamoto. The interview covers characters they wanted to add to KoF XIII, but couldn't. Those include Adeleid, Oswald and Malin! He talks about the notion of branching out into other game genres (including a new free-to-play Metal Slug game in the works), and a possible new crossover with Capcom or any other willing companies if there's enough demand. While most people want a Capcom vs SNK 3, I would go ballistic if an SNK vs Capcom 2 happens!
Now I'd really like to see a post-EVO interview with Mr. Yamamoto, especially after the ending ceremony for KoF!!
