Difficulty of Playable Factions in RTW based on what I have seen (don't flame please)

I was under the impression that you could change some of these settings to your desire, like Campaign difficulty (similar to the MI setting) and Battle difficulty (the tricks of the AI in battles). I thought I read something like that in one of the previews as well...

Yep, there are two different difficulty settings that you can set at the start of a campaign: campaign difficulty and battle difficulty. Which is a nice idea I think.
