Treyarch, the studio behind Call of Duty: Black Ops, is bringing the Call of Duty series to a "new console" according to a job ad on the developer's website.
The hint comes in a call for a senior platform engineer where the studio lays it out pretty plainly:
"Treyarch is seeking a Senior Platform Engineer for a position on the team bringing our hugely successful game to a new console."
Which new console we're talking about exactly is still unclear. It's likely that Treyarch is talking about an announced but as yet unreleased platform like the Vita or the Wii U.
However, there's always the possibility that the Call of Duty studio could be preparing for the next generation.
