No beef, really. I just draw a distinction between what might foreseeably happen in a new, 2.0 version vs. what would occur with house rules/tweaking.
Given the WotC delivery on generic sculpts, no cold, hard, IPCs, and the like, I doubt anything like cavalry would make an appearence. Changes in the rules, however, are a more likely thing. Africa, especially, needs some simple but specific rules (ie. restrictive movement, reduced unit attacks/defense, etc.)
However, they would be something I would consider adding in a house-rule/variant derived from A&A 1914. But they would need to add something significant or unique to the game play. I know that’s been discussed in other threads, and personally, I’m split on the issue. I am more likely to add trains and fortresses to the mix (e.g. the latter did significantly affect the course of the war, such as in Liege or Przemsyl). It gives another focus for artillery/infantry, and siphons off troops from the otherwise attritional wars o’ stacks.
Point being, I’m just drawing distinctions between “what might” and “would if”. And nothing personal was intended.
