All joking aside, I agree that Kyo deserves a place in the marketing. Terry, Ryo, Haohmaru and Kyo should all always be represented in the marketing. For SvC Chaos the marketing should reflect the product but Terry is the top dog and, plain and simple, that is why they're doing this. He's the guy. Once Sakurai chose him for Smash, and once SNK agreed to it, the message was clear.
SNK is in a place now where they obviously want to benefit from the rub of more successful companies. Those companies don't see Kyo as 'the guy' anymore (and it's doubtful they ever did). SNK is rolling with that. Maybe the first smart thing they've done in a long time.
