However, that would still be a significant drop from 144,000 attendees at CES 2007.

The prospect of a reduced audience hasn't fazed companies like Intel, Microsoft, Hewlett-Packard, IBM and Dell from showing products in or around the show. Overall, 2,700 companies will be present at various locations, including the Las Vegas Convention Center and surrounding resorts and hotels.

A standout at CES could be netbooks, small laptops used for basic applications such as Web surfing and e-mail. Intel defined the category with its Atom processor, which was then solidified by the success of Asus' Eee PC. The show could see an evolution of netbooks, with features like touch screens attracting interest. Asus will likely show a touch-screen netbook, and Intel is showing off its Convertible Classmate, a netbook with a touch screen that swivels.

Via's elusive Nano processor may also make an appearance. Rumor has it that Samsung will show its NC20 laptop based on a Nano processor.

Some of Intel's competitors, meanwhile, may try to redefine how people think of netbooks by pushing more advanced capabilities. Advanced Micro Devices and Nvidia may talk more about boosting graphics on netbooks. Freescale and Qualcomm could demonstrate netbooks with more communication-savvy chips.
