Creutz expected more growth from the Call of Duty franchise in 2011 due to an expanding console hardware install base, but did project an ongoing decline in the franchise's tie ratio. However, DLC sales would likely grow. Cowen's predictions for next year were based on assumptions that Blizzard titles Diablo III and StarCraft II: Heart of the Swarm would arrive during fiscal 2011. This meant that Cowen believes Activision-Blizzard "shares can outperform the market by at least 20% over the next 12 months." For 2012-13, it hoped for good things from Activision's secret Bungie game, Blizzard's next MMO (rumoured to be known as Titan) and a spin-off Call of Duty series from Sledgehammer. Cowen felt that this franchise extension could "debut with at least 5 million in worldwide unit sales" but expected it to be delayed until as far as 2013 due to Sledghammer's alleged assistance with Infinity Ward's current title.
