It appears from what Engadget has heard - anonymously of course - that HP's got two Palm webOS tablets: a seven-inch (180 x 144 x 13mm) model code named Opal and a bigger iPad-size nine-inch (241 x 190 x 13mm) model code named Topaz.

Topaz may or may not be out in March and, if not, then, maybe June. Opal looks constrained until September.

One might expect a 1.2GHz processor; "tens of gigabytes" of cloud storage for storing apps, apps states and documents; intimate call and content-sharing between Palm's phones and tablets; an Apple AirPlay-like "Tap-to-share" feature that transfers files by bumping the devices together; HP Beats "professional-grade sound"; a Touchstone-style programmable wireless charging dock; un-Apple Adobe Flash support; front-facing camera and microUSB port; Wi-Fi and Wi-Fi+3G (AT&T and Verizon versions eventually); and the ability to run "up to 20 applications simultaneously."

Remembering that Palm chief Jonathan Rubenstein just joined the Amazon board, PreCentral.net wades in to say that it's heard that the widgets will be tightly integrated with Amazon services like its unbox movies, music store and Kindle.

HP reportedly filed for a trademark on the name "HP Touchpad."

The picture should become clearer on February 9, when HP has scheduled what is assumed to be a Palm announcement.

Oh, yes, almost forgot, Engadget's got some leaked pictures.
