The Warrior

Shameless VDV hint there?

Will we ever see this bad boy in game?

I'd be all over a Philippines 1944 game.  It's one of the places in the pacific where there was enough room for larger actions, urban fighting, armored warfare, paratrooper assaults and all sorts of goodness.  You'd be able to use US forces that broadly look like Normandy with a few quirks, but the Japanese would present a very different military force, and throwing in the various irregular factions could make for some really awesome missions.
 
Korea 1950 would be awesome too.  Light on the AFVs, but some really awesome stuff to work with in terms of scenarios.
 
Also a good late 80's Fulda gap would be mindblowing.  I'm partial to 1989 because it seems best positioned to offer very late cold war equipment (M1A1HAs, T-80Us, etc), while not getting into weird alternate history stuff, and still being reasonable to see a lot of the cold war standbys (and bypassing the "EVERYTHING IS NUCLEAR" phase of NATO).  
 
In terms of near future:
 
1. Korea. The DPRK is less likely to be a threat these days, but it could be fluffed a bit and the PLA might make a good inclusion.
2. Iran/Egypt.  We're running out of conventional threats in the middle east, and CM does COIN pretty good...but ISIS just is not going to let us do the tank on tank, company sized elements of troops that CM does very well.  Iran after a turn for the worse offers something similar to what Syria used to have in CMSF.  Egypt could be fascinating if we assume the current government crumbles and the Islamic Brotherhood comes back for reals.   On the other hand, just having a general purpose "middle east" game that modules in more than just Bluforce for the theater from the base game could be cool (so base game is US Army and Iran, Module 1 is Egypt and Israel, Module 2 is British Army and Syria/ISIS or something).

Kieme CMBS T-84 Oplot - green version
 
I owed a Bradley veteran one plain green, dirty Oplot...
 
 
Please note that this mod is not compatible with the old T-84 Oplot mod with digital camouflage, use only one of the two mods, pick the one you prefer and unistall the other one.

M-36 is pretty much a must-include for anything that covers the post August 1944 timeframe.
 
After looking it up, the first time an T26E3 (as they were called until March) went into combat the last week of February.   If the Bulge module covered the final reduction of the Bulge itself and the follow on offenses, having them in would be pretty cool.  Of course the other thing would be figuring out just how they were supposed to be included, the ten or so tanks that went to 9th Armored were deployed in  platoon elements, while the 3rd Armored ones wound up being basically deployed as a replacement for one tank in an otherwise Sherman-ed up platoon.  
 
So I guess at that maybe it'd be something like a super high rarity upgrade for a platoon (much in the same way you can upgrade M4A1s to M4A3 76s or something), or an option to include it as a very expensive platoon with a rarity discount (basically you should either see one Pershing, or five, and nothing in between, or more)

I seem to remember Steve saying they were planning on doing a Bulge Commonwealth module and a late war module taking us to the end of the war including the possibility of some designs that never saw combat e.g. the Maus. Personally I don't think they Maus would ever have gone into production even if the prototypes were completed in time. Maybe the Panther II( I think it was called) would have been more likely.
