"But who is Nerve Software?" you're probably wondering. Nerve has done a bunch of contract work for Activision in the past, including Treyarch-developed James Bond title Quantum of Solace, as well as ... Call of Duty: Black Ops (the first one).
So, there's one more lead in the "Activision and Treyarch are probably gonna release Call of Duty: Black Ops 2 this year" news cycle. Between domain registrations and reported retailer listings in Europe, we're thinking an announcement can't be too far off. Activision and Nerve Software had yet to respond to request for comment as of publishing.
Update: Mr. Beyer (or someone on his behalf) has taken down his LinkedIn page, it would seem. We've still yet to receive responses to comment requests from him, or Nerve Software, or Activision.
