I'm thinking of buying the Razer Mamba wireless mouse because I'll a laptop gamer and I was looking for a nice gaming mouse. I was looking at the mouse on "razerzone.com" and I saw a banner at the top saying "New Edition!" I'm confused if that means there is a new 2013 edition or a newer version of 2012 edition. Can anyone tell me if Razer has made the 2013 edition of the Mamba or is it still in the 2012 edition?
