The Verizon inventory system has really been letting go a lot of device information this weekend, the Prime and the Vigor being two, now the upcoming Xoom's are next in line. Just today this screenshot was posted of Verizon's current and future inventory. The Xoom 2, being called the MZ517 Pasteur, was added just today. The device is rumored to have a faster processor at 1.2 Ghz, a faster RAM chip, much slimmer, and all around better. Now for the other Xoom, called the Fleming in the screenshot above, is just the 7 inch alternative to the Xoom 2.
Both device are rumored to be coming within the next few months, and so keep an eye out for them.
