I agree.
Although KoF is huge in Central and South America and China; it has been THE fighting game franchise for decades. And in recent years, the company has been on an upswing. I mean, 6 years ago, I couldn't imagine SamSho getting the love it has, Geese being in Tekken, Kula and Mai in DoA, etc.
This is a lot for me to process, but SNK had a huge impact on the industry, and especially the FGC (and as aforementioned, even more so in certain parts of the globe where it reigned supreme). Whoever we get, if anyone, is going to be awesome, and they're going to introduce more people to their games, which is always a plus. With that being said, as unlikely as it is, King would be a dream for me, gratuitous English and all; she's just really cool and an AoF and KoF rep. Athena seems a little more likely, and is cool, too. Mai is also feasible, as are the big names like Terry, Kyo, etc. That's not even including non-fighters like a Metal Slug rep. This is just... so great lol.
Random tangent: Capcom vs SNK 2 is arguably one of the greatest crossover fighting games of all time. We might be able to reenact a part of that in Smash. Good Lord.
