Droid Eris: Verizon's other Android phone?

We're learning a lot about Verizon's Motorola Droid (with more to come soon), but what do we know about the Droid Eris?

Also called the HTC Desire, the Eris (and the Moto Droid) will be a part of a series of Google Android devices for Verizon Wireless. According to Gdgt, preliminary specs include a 5-megapixel camera, a microSD card slot, EV-DO, a 3.2-inch display, and (thanks to the Boy Genius Report) a 528MHz processor. Official photos are nonexistent at this point, but the Eris should have a HTC Hero-like a trackball for navigation.

Verizon hasn't announced a release date, nor has the carrier even confirmed that the Eris exists. But the clever AndroidGuys got a tip that Verizon employees are receiving Eris training. That makes a rumored November 6 availability quite likely.
