I could tell from the screenshots on the front page it was either higher res or more bitmaps.
That said, I think it was a valid move to give us more pixels for the B-29. With that in mind, will we be seeing more pixels for the other heavies? While the B-29 is a huge huge plane, the B-17 and B-24 aren't too far behind. Their bitmaps are a bit scrunched and compacted.
I believe we should not see 2048 for fighters or even light/medium bombers, but for the 4-engine heavies, will we be seeing more resolution in the future?
