This year, the buzzwords look similar to last year, including "connected," "always on" and "voice recognition," whether in new, more powerful phones and tablets or in cars or even watches.
"This year there's going to be a focus on connectivity and mobility that continues the momentum we've seen for the past few years, even though we may not see quite so many big announcements by (mobile) carriers as we did last year," said Ross Rubin, executive director, Connected Intelligence, at retail research firm NPD Group.
The latest crop of light and thin laptops, which Intel Corp has dubbed "Ultrabooks," is set to dominate the hardware displays, from the likes of Toshiba Corp , Asustek Computer Inc and Lenovo Group Ltd.
On the other side of the floor, the latest high-definition, Internet-enabled TVs from Sony Corp, Panasonic Corp, Sharp Corp and LG Corp will also draw crowds.
Wireless carriers AT&T Inc and Verizon Wireless are expected to unveil devices to take advantage of their new high-speed networks, and phone-maker Nokia is preparing to reintroduce itself to a U.S. audience with new handsets running Microsoft's latest Windows software.
