Namco Bandai Teases The World With An “X”

The say "X" marks the spot, and it seems that Namco Bandai has taken this to heart with their latest teaser trailer, which is just this X. 

As you can imagine, speculation is already stirring that it's a reference to Tekken x Street Fighter, but since Street Fighter x Tekken just released, that seems kind of boring to me. I know that Namco Bandai and Capcom have forged a little crossover partnership pact, but are they really going to be so predictable and boring to create such a similar game so soon after their last crossover? 

Maybe this is a whole new crossover in play. What if it's Tekken x Tatsunoko? Or Tekken x Soul Calibur or Tekken x insert-non-fighting-game-here-that-will-blow-everyone's-minds?

Ah, who am I kidding. It's most likely Tekken x Street Fighter, as we seem to have run out of imagination as of late.
