A few new screenshots have been posted by IGN.

I'm especially intrigued by the first screenie, which appears to show both Soviet aircraft and *two* different types of Allied aircraft. I believe the one Allied aircraft (on the right-hand side) is the previously-mentioned Century Bomber, but I have yet to see anything on those Soviet warplanes. The other Allied air unit looks like it may be more of a fast-attack craft (perhaps acting as escort for the bomber?), but it's hard to tell.
