More than 3,800 tech companies will be in Las Vegas starting Thursday for the 2017 Consumer Electronics Show.

CES is an annual gathering for tech-related ... well, anything really. Engadget says expect lots of Microsoft Surface competitors, some phone news from BlackBerry (though CES isn't generally a big mobile show), and a lot of TV/home theater news.

Best Buy will have some high-level execs there. They meet with vendor partners and scout products that haven't yet hit the market, a news release says. They even have a page specifically on their site for CES products.
