I think these publishers and characters are still left on this game of Guess Who?
Namco (Tales of, Tekken, Xenosaga, Soul Calibur, and Dark Souls. I guess Katamari, Klonoa, and Taiko too, but those wouldn't be too exciting)
Capcom (Phoenix Wright is what's left standing. If we're reaching, Amaterasu and Morrigan)
Square (Idk, but it's still possibly Square)
Disney (Sora)
Activision (Spyro's still possible, I think)
Konami (Contra, Frogger, maybe even Silent Hill)
Bethesda (Elder Scrolls and Fallout are still in the running. Wolfenstein would not get in before DOOM, so I'm counting Blazkowicz out)
Level 5 (Layton or Jinbanyan)
Team Shanghai Allice (Touhou)
Arc System (Ragna, Sol, River City, or Double Dragon)
Marvelous (Story of Seasons or Rune Factory)
Take-Two (Imagine the reaction CJ would get)
Valve (Chell and Heavy haven't been deconfirmed yet, right?)
Spike? I don't even know. (Get hyped for Junpei, boys)
Let's bet on who's getting "deconfirmed" next. I bet Vergeben will say Level 5, Arc System, and Spike are out before Sabi says Tales of is in.
