I don't think this is a new expansion. As I speculated here (http://planetcoh.gamespy.com/fullstory.php?id=153176) last week, I am reasonably sure that this has something to do with the current DLC Relic is working on. It doesn't make much sense to develop a single-player campaign DLC due for release later this year, then to follow it up with an expansion in early March that would, in theory, contain two new campaigns. My guess is that this is a retail collection of the DLC that Relic is working on, which makes a bit more sense considering the name could be referring to multiple DLC campaigns as the tales of valor.
