Simply put: Ubisoft wouldn't know a decent marketing if it was a bat which was used to beat Ubisoft to death with. They never got a marketing campaign right in all the time with the original Il-2 line ... never. I really hope the contract between 1C and Ubi runs out before the sequel comes ... maybe a new international publisher would do better.
EDIT: And a personal comment. All those facebook/twitter/whatever stuff; I don't know if I'd call marketing there positive. I, for sure, have no account in such systems. I don't want to do a virtual striptease and spread my personal data.
