4-Armor Shermans in Ardennes 1944!!!

[triangular_cube]

If it does end up being the case that the system is going to feature AV4 Shermans going forward, is PGHQ going to interpret this as errata for the legacy game listings and use the "Heavy" Sherman unit types or will these continue to be the "base" M4 units?

Two examples of similar units that come to mind were the nerfed Marine INF units, which did replace the old ones in the listings, or the PZIIIH AV3 > AV4 alteration which never even warranted a separate unit card. 

I guess I just don't know what to expect.
