Well, they were all unbundled, does that count as an update? =P

nah I was thinking more missions. I think they should add D-Day as a mission for the american side, as it played a big part in the war along with other soviet and german missions

Alot of what you may want is probably covered in the numerous spinoff games using the blitzkrieg engine or in one of the mod packs.

The game does in fact include D-Day landing missions in the Rolling Thunder expansion as part of the Patton campaign.

If you like the engine and gameplay I would highly recommend the spin off game Stalingrad which is available on Steam - it ups the historical accuracy and is one of the best uses of this engine I have seen.
