Will we see the successors to the Halo franchise soon?

Gematsu reports on the LinkedIn resume of Microsoft Studios senior product manager and planner, Jonathan Browne. According to the resume, Browne has worked on four new, unannounced IPs.

Under the "Jonathan Browne's Experience" section, it says, "“I have been the primary product manager on four unannounced new IP and have been a key contributor to bringing these IP from the very early concept phase through green light to production."

No other details indicate whether or not we'll see any of these IPs during the Xbox 360's lifetime or if they'll be unveiled with Microsoft's next console, but we'll keep you updated on any news that might surface.

So, let the theorycrafting begin! What are your guesses about the new IPs? More space marine goodness? Or maybe they'll be drastically different and more grounded in reality? Let us know your thoughts in the comments!
