AI question.

[stormbringer3]

I've just downloaded the latest patch. My question is that although the patches always improve the game in many areas, there doesn't seem to be any obvious AI enhancements. Does the game engine's age prevent any meaningful enhancements?
Steel Panthers is still my favorite tactical game. I usually play a long campaign and the challenge is basically how large will the enemy horde be in that particular scenario of the campaign.
Thanks for any opinions.
