Winter and Summer would be pretty much the same - movement penalties in the appropriate provinces.
In terms of battles, I doubt wind would have much effect on bullets, and I don't think CA would implement a wind feature 'just' for the Indian (American and Asian) and other 'primitive' factions.
In terms of campaign length, I think it's a very much-needed feature. But I spose if they don't implement it, some modders will.
