Eric Hirshberg, CEO of Activision Publishing, says the company isn't changing its sales projections on the Skylanders franchise, or this fall's Skylanders: Swap Force, in the face of Disney Infinity.

"We're still bullish on our projections. We feel like it was only a matter of time, given the scale of the success of Skylanders, that other competitors entered the genre. That's to be expected," said Hirshberg.

"I get this question a lot on Call of Duty. We have tough competition every year. We have tough competition in every category we play in, it's a part of the business. We try not to focus on it. We try to focus on making the best games we can and exceeding the expectations of our fans and bottling magic."

Skylanders has surpassed $1 billion in lifetime sales since launching in 2011. Disney Infinity will launch this August.
