What I'm hoping for are just expanded features of the original Medieval. Personally the mechanics of that game were outstanding and should they just add Rome style graphics to that I'd be a happy man!

Anyway, from what's been put out so far it looks like I'm not too far from the truth, although I think they've concentrated on the AI for both campaign and battles (unit by unit and overal). So, rather than fix something that isn't broken they've just taken what they've added to Rome and BI that's found rounded approval and added these features to the new Medieval.
