VIDEO GAMES: Blizzard Free to Play?

Rumors have surfaced today that Blizzard, developer of World of Warcraft, Diablo and Starcraft, is making a new free to play game. That's pretty much the extent of the rumor, and it's just that...a rumor. We already know they're working on their next MMO code named Titan and it remains unclear whether or not this free to play announcement refers to that game or not. I've always thought that Blizzard should work on more that just their 3 pivotal franchises as I'd love to see more titles from the company, but only time will tell whether or not this new rumor has any truth to it. What would you like to see from Blizzard in the coming years? Excited for Diablo III? Mists of Pandaria?
