Titanfall: 6-vs-6 Multiplayer Maximum

According to this news post over at Blue's News, Titanfall will be limited to 6-vs-6 multiplayer matches.
Respawn Entertainment's Vince Zampella tweets about multiplayer support in Respawn, saying their upcoming mech game will support six-on-six multiplayer games, saying limiting this to 12 players is best for game balance: "6v6 is max player count. Turned out to be the best balance with ai for us," then clarifying "that's humans only count. There are lots of ai, everyone can have a Titan in follow or guard mode too."
