Has It Been Changed in CMx2?

[Extraordinarius]

I loved the system, but CM one drove me nuts because of several equipment/OB errors.  I always wanted to play the Americans, but they were so severely crippled that it became too frustrating and sad to play after both of my like-minded frequent opponents, who would cooperate making adjustments, died in the real world.  I am now contemplating purchase of the new game.  What I want to know is whether any of the following have been corrected in the current iteration:

1)   In western front CM, the American artillery cost as much as the German.  The Allies had four times as many gun tubes as the Germans, each Allied tube had four times as much ammunition and the flexible control system gave units access to the support of more batteries than German units had, but all this was represented by penalizing the Americans.  They received no discount for huge availability of artillery.  The U.S. units of fire were twice as large as the German, costing so much that it was generally not possible to buy them.

2)  American 81mm M1 mortar drove me particularly wild.  The British "3-inch" mortar was actually of 81.2mm caliber, and after the Normandy landings a majority of the shells fired by them had originally been manufactured for the U.S. weapon, but apparently the game designers decided that Britain got all the heavy shells. 

3)  The Germans had their 81mm mortar upgraded.  Because of transport problems in foot infantry units a cut-down version had been put into production.   By 1944 the original 8cm Granatwerfer 34 had been reserved for regimental artillery units, while companies and battalions were equipped with the Kurzer 8cm Granatwerfer 42, which fired the same ammunition as the old weapon to about half the range.  On anything but a small map that would be significant.

Do these problems still exist?
