Every year, tens of thousands of reporters, analysts, and suited-up businesspeople descend upon Barcelona for the Mobile World Congress trade show. Mobile World Congress, or MWC if you're in the know, is the largest trade show for mobile technology: phones, networks, hotspots, infrastructure, and more phones.

In recent years, MWC has been fairly sleepy, shifting from a consumer-centric show with big product launches to a more business-focused one that catered to infrastructure announcements. But this year it appears the show will swing back in the other direction: there are lots of companies that will be at MWC this year, and some major product announcements are expected to drop.

The fun starts on Sunday, and we'll be there covering it on the ground with hands-on reports, live blogs, video, and more. All of our coverage will be neatly organized in our special MWC 2015 hub (bookmark it!). But to whet your appetite for now, here are nine things plus one wildcard we expect to see at this year's MWC.

Expect phones. Lots and lots of phones.
