Sony has launched a teaser ad campaign for a new 'revolutionary' Vaio laptop that appears destined to debut at January's Consumer Electronics Show in Las Vegas.

Promising to 'change the way you think about laptops', the company's New Zealand subsidiary has launched a countdown teaser campaign on its Web site entitled "The wait is over."

The site is offering no details on the new Vaio laptop until January 9 -- which due to the time difference between New Zealand and Las Vegas means the unveiling will come a few hours after Sony CEO Howard Stringer delivers a keynote address at CES.

Gadget blogs were recently set buzzing after an upcoming Sony laptop appeared in a regulatory filing on the Federal Communications Commission's Web site. The machine, identified as the PCG-1P1L, is a Windows-based machine that offers several connectivity options including 3G wireless.

Most details of the machine were temporarily withheld from the FCC site at the request of Sony however a picture of the base of the machine and the product ID label indicate the computer is approximately 22 cm long by 11 cm deep.

That would make it smaller and more compact than most netbooks but whether it's a netbook or a more powerful computer is impossible to tell.
