A few new trademarks from Square Enix have popped up recently, but only one of them gets me really excited. Sure, "Wizardlings" sounds cool, we already know what "Agent 47" is, and it looks like we're getting something called the "Ultima Box." I bet I know what the latter is.
But the most exciting of the trademarks is "Circle of Mana." This could be the next title in the Mana (or Seiken Densetsu) series of games, and would be the first since strategy game Heroes of Mana.
I'm betting on a Tokyo Game Show announcement, and hoping for a console release, though I think a portable (3DS/Vita) is more likely.
