You're dreaming, new char will be far more too expensive, if they had some it will be new ex, like robert or yuri i guess.
And snkp didn't show any willingness to add some for now, considering the fact making a new character took them one year from scratch for arcade version, i believe we won't see any for a while.
SNK is one hundred times smaller than Capcom, and 2d games aren't 3d, it's far cheaper and faster to do char on 3d than in 2d.
