The phone showed up briefly on Google Play before Google took it down. The blog Droid Life took a screen grab of the listing, which placed the price at $409.
The listing in Google Play also may confirm reports that Google plans to sell the next Nexus directly, a la Apple. That was also the game plan for the Nexus One in 2010, but Google eventually pulled the plug on that effort because of lack of demand for the $529 model.
Though the report lists Jelly Bean as "Android 4.1," other rumors have said that's the code-name for Android 5.0. Google is said to be switching strategies for Jelly Bean, allowing multiple manufacturers early access to the OS. Previously, Google had partnered with a single manufacturer to provide a "reference" for other models.
More details about Jelly Bean will likely be announced at Google I/O, the developers' conference, next week in San Francisco.
