Not a ton of details here, but Russian website TheVista.ru has turned up some seemingly legit materials for a hereto unheard of Metro Mouse from Microsoft, which is apparently a new addition to the company's BlueTrack line -- and Microsoft's latest use for the "Metro" name. At just $20, it'd also be the cheapest in the line and, like some of the other models, it's designed to be used either left or right-handed. Assuming this leak actually pans out, you can look for this one to be available sometime in March.
