Recently Frank O'Connor sat down with Joystiq and shared that the 343 Industries creative is weary of the market becoming over-saturated with Halo products.

"I worry about that constantly."

O'Connor suggested that the Halo franchise wasn't currently clogging the market.

"All of that stuff has existed in the past, and it exists because of one simple reason, which is demand. We wouldn't make it if we weren't continually being asked for it," he said.

"We obviously turn down almost infinitely more stuff than we actually produce, but when we produce it there's a good reason and a good plan and a strong demand."
