I agree...a Smartphone/Tablet announcement is likely. Intel China head Sean Maloney has done a web chat yesterday about Intel pushing to get a major market share in Smartphones/Tablets in China. So Intel will most probably announce some design wins at the show.
Also, since the show is more technology-oriented, I would expect some details on their dual-core Medfield as well as the next-gen Atom architecture.
=========================== Intel plans to win in China's smartphones and tablets market
"Our strategy in China now is to win with smartphones and tablets. We are making progress on it!" Intel China chairman Sean Maloney said during a chat with users hosted on Chinese social networking site Sina Weibo.
To compete, Intel has been developing new chips, including mobile chip Medfield, that aim to offer better power savings and fast computing speeds. "This requires strong processing power and this is where Intel's silicon strengths come into play," Maloney said.
