I'll probably start out the same way I started in MTW - on English soil. I'm not sure of the direction I'll take, though. I might try and establish some sort of North Sea-based empire, Britain, Flanders, Friesland, perhaps Scandinavia, that sort of thing - not bother too much with continental politics. But then, I had wanted to do just that in my current English campaign, before the continent sucked me in anyway. Then I lost both England and France, and conquered Spain instead.
As long as MIITW campaigns will be as interesting as that, it won't really matter which faction I'm playing.
