Ok, I'm just going to mention this here because it seems to be related to what we're talking about. I already mentioned it in the Twitter discussion thread but no one seems to care over there (I'm not sure why, I was excited by this).

When I was reading the provinces and authority preview, I just noticed that at the end of the guide, there is a sentence that says that the previews are the "precursor to a number of Tutorial Campaigns." It doesn't sound like they will be alphas, but it does give the impression that we are to expect more than just the Gaza Campaign for tutorial campaigns.

Take a look yourselves (it's the link in the post towards the bottom of the page about new gameplay features), does anyone agree with my conclusion?
