CES looks to be the launchpad for T-Mobile’s upcoming Un-carrier announcement (12, is it?) as T-Mobile recently released a cryptic teaser showing a bunch of people asking T-Mobile CEO John Legere, “What’s Next?”

Unfortunately, no additional details were revealed at this time. During the teaser video, John Legere states “Everybody’s been asking for this one. You’re gonna love what’s next.” The only other Un-carrier announcement T-Mobile has made at CES was Un-Carrier 4.0 where T-Mobile began offering to pay ETFs for customers who wanted to switch to T-Mobile, but were stuck on a contract with another carrier.

T-Mobile’s CES press conference will take place at 11AM on January 5, 2017.
