Couldn't the Vigor just be the name for the Puccini? 1.5Ghz LTE with the same screen res as the Xoom?

If you look closely the Vigor is listed as coming out 10/5/11 and the notes say replacement to the Thunderbolt. I am all in!
Need more information about the Vigor - odds are it won't be out on time just like the rest of the lineup.
Also I don't buy the leaked stats - they can't get any other phone they have to get good battery life and this will be a hog.
