After Captain Price voice actor Billy Murray reportedly outed his involvement in Modern Warfare 4, Infinity Ward has spoken out to state that that his claims are "not true," but didn't discuss whether or not a direct sequel is indeed in development.
"Interesting news today, but it's not true," reads Infinity Ward's missive on Twitter. "We've not talked with any voice actors, so all news is speculation."
It's worth noting, however, that they didn't deny the existence of Modern Warfare 4.
Is this news? Maybe. Probably not. Either way, consider the subject closed until after Black Ops II releases.
