Mark it under rumours, but word on the street is that Palm is actually working on three devices on the webOS platform. While we are all familiar with the Pre that hits the US on June 6, there are two more devices in the works.

According to our source familiar with the matter, there is one device that will share the same form factor as the Treo Pro – a bar phone with a touchscreen display and physical QWERTY keyboard. The other device, will compete directly with the iPhone and will be an all-touchscreen sleek device with no physical keyboard. For all its worth, we’ll wait for the first reports on the Pre before betting our chips on the other two.
