Spoiler: I don't know. But it looks like the Vigor isn't the only phone HTC has in the pipeline. This is HTC Holiday, and it has a California license plate. And a 4.5-inch qHD screen.
According to word on the street, there'll be a 1.2GHz processor whizzing away inside, so won't be quite as powerful as that rumored Vigor. A possible 8-megapixel camera on the back, and 1.3-megapixel on the front have also been suggested for this AT&T-bound behemoth. [XDA Developers forum via SlashGear]
