Palm is set to preview this week its latest incarnation of mobile operating system — Nova — in a bid to re-ignite the company as a smartphone leader. Latest developments say that Palm will also release a new device that runs Nova as well. The unveiling is expected during the Consumer Electronics Show (CES) 2009, which starts on Thursday, January 8 in Las Vegas.

We have information from a trusted source that the latest Palm smartphone running the Nova operating system will be launched Thursday. The new phone will have a full QWERTY keyboard that will slide down under a portrait-oriented touchscreen. We’ll have a mock-up shortly.

The new operating system is described as “amazing” and there will be a full software bazaar on launch. It will have media playback functions along with standard Palm calendar, email, and contact functionality.

As expected, the phone is described as “iPhone-like” and will probably be sourced by HTC like the Palm Pro. The official Palm announcement should happen this Thursday at CES.
