Sagat, the "Emperor of Muay Thai" and original Street Fighter boss, was more or less confirmed with another Street Fighter X Tekken teaser from Capcom. The trailer may not show much, but the bandages, immense (and shirtless) shoulders, plus just the teensiest glimpse of blue shorts pretty much give it away.
So while not unexpected, it's nice to assume the scarred giant will be appearing in the game. Look for him and try to resist teaming up with Bob from Tekken - just try to resist the pun! - in Street Fighter X Tekken, due in 2012.
