Various US retailers have changed their estimated release date for upcoming PS3-exclusive shooter MAG. The general rule of thumb is that if a single retailer has a funky listing, it's usually an error -- but when two or more retailers have MAG listed as releasing in January, something begins to smell fishy. Of note is the fact that both GameFly and GameStop are listing different January dates.
While Sony hasn't "made any announcements in regard to a date for MAG" and is "assuming that the retailers are speculating in an effort to start preorders," we were told by a Sony rep at E3 that MAG would be part of the company's Christmas lineup. Without it, we're looking at Ratchet and Uncharted having the entire Christmas stage to themselves.
Another interesting thing to note is that European retailers Play and Game have the game listed for a November release. In short, we have no idea when this game is coming out, but at least we're not the only ones.

seems like a lot of games are moving there dates about which is not a bad thing as a shed load of games seem to be all coming out at once but as consumers we need to know so we can spend the money on other products
