Do we know what a "soft launch" actually means?
After thinking about it, I'm thinking it means simply that the launch date hasn't been set yet. Like "tentative launch".
As has been said, I can't imagine they will just magically appear on the shelves one day. It's going to be priced as a high-end phone, and they will market it as such. Also, there's no way they want exclusivity to just ignore it and keep it out of competitors' hands just for spite or something.
Doesn't make sense, unless there's some blood feud wife-stealing subplot between the CEOs of Verizon and Google.
