We know that AT&T is getting the Nokia Lumia 920 and 820 Windows Phones. T-Mobile is slated to get the Lumia 810. We've also seen a Nokia Lumia 822 floating around that is headed to Verizon.
We may need to add another number to the mix, the Nokia Lumia 922. A series of tweeted rumor is out there by @NokiaPureView who is claiming to have handled a Verizon Lumia 9XX (presumably the 922). The tweets mention that the mysterious device has a "matte finish, Pureview, is thinner, lighter and better."
Granted no pictures were offered on this mysterious device and according to @NokiaPureview Nokia CEO Stephen Elop doesn't want any pictures taken of the Verizon Windows Phone.
