Quite simply, the only way we knew of the Desire/Eris was an inventory screen shot in early September and a picture from the press conference in early October, and even the latter was pure speculation about what Google's CEO was actually holding. That is pretty scant compared to what gets leaked sometimes. There was no close-up shot of this phone confirming it's existence on Verizon until about 2 weeks prior to release.
