Yep, was just about to post this. And I believe you can take that one character (Jago) into online multiplayer as well. OP should be updated (or new thread?)Gamespot stream confirmed that it's offering both a full version and a 'demo' version where you get one character and the entire SP campaign and can trial (I think) new characters before you buy.
Looked pretty neat in the gameplay footage.
To reiterate, it's offering a full version that includes all the content and a 'demo' version that only offers one with the option to buy more.
