Metal Gear Rising: Revengeance, a Kojima Productions and Platium Games joint, is out in February 2013. It might not be exactly the kind of Metal Gear game you're after, but it might be exactly the kind of Metal Gear trailer you're after.
I really wish this game didn't exist. The version that KojiPro was working on actually retained that Metal Gear look to it, but this just looks way too over the top and corny. I sincerely hope this isn't a part of the MG canon. Raiden's story ended just fine in MGS4. Kojima, as a long time MG fan, handing thos off to Platinum Games was a big mistake. Rewind back to 2010 and just take over development of the Rising your team had created. Plat's version doesn't look at all MG. As another Bayonetta or DMC, this would be great.
