Update: here's the trailer in good-o-vision, on the official COD YouTube account. It reveals that if you pre-order the 'Legacy Edition' of Infinite Warfare, you'll get that recently revealed COD4: Modern Warfare remaster bundled with it.
Well, here it is. A reveal trailer for the teased Call of Duty: Infinite Warfare, , and in a million potatocam YouTube videos, one of which I'll embed below. One suspects this trailer has arrived slightly ahead of Activision's , given that the hasn't yet posted anything about it, and hurrah for that.
As you can see, COD:IF will be out November 4, and will feature a big battle where an armoured vehicle thingy rolls down some stairs. Also, you'll be able to blast off into space! Fancy that. I should probably write more, but I wanted to post this posthaste, in case it suddenly disappears from the interwebs.
