Call of Duty: Modern Warfare 3 co-developer Sledgehammer Games has confirmed that it isn't involved in the development of the newly announced Call of Duty: Ghosts.

"Congrats to @InfinityWard on #CODGhosts!" Tweeted the studio. "Our team is heads down on our next project, but best wishes to the hardworking team at IW!"

Sledgehammer stepped into the high profile world of Call of Duty when it was drafted in to assist Infinity Ward on Modern Warfare 3, following the studio's employee exodus in early 2010.

Does this mean Sledgehammer is working on something new or yet another Call of Duty title? Last year it was reported that Sledgehammer had indeed returned to the Call of Duty franchise, with a job advertisement for a Senior FX Artist mentioning the "next Call of Duty game".

Neversoft, too, is believed to be working on the Call of Duty franchise, perhaps alongside Infinity Ward on Ghosts.

Do you trust Infinity Ward to go it alone on Ghosts or would you rather the studio was given a helping hand? Share your thoughts in the comments below.
