A Palm insider has given us access to information that definitely and finally confirms the existance of two Palm devices currently codenamed Zeppelin and Skywriter.

The document that we are looking at covers a developer program that allows Palm’s favorite developers to make their applications ready for the two new devices AND maybe even comarket them with Palm. All applications must be submitted by May the 30th - this could point at a launch of the device(s) in Q3 2008.
