Spotted the following listing for The Sims 3 Commemorative Edition over at the other day.  No given details on this product at the moment other then the fact it is released on the same date as The Sims 3 Ambitions.  My guess is that this is another repackage of The Sims 3, but with the 10th Anniversary Sims book that is rumored to come out.  Do we really need another release of the base game?
