Sony skipped out on Mobile World Congress last year in terms of having a big event of their own, but they seem to have enough to talk about this year that they're getting back on the stage. The company started sending invites to press for a February 22nd. We haven't heard much about Sony's 2016 plans to date, so no one is yet sure what's in store. It must be something big if they're holding an entire event for it, though.
