Unfortunately, nothing is certain about what Xiaomi has planned for the February 12 event in the US, and much speculation thus far has centred around no big announcements for the US. But According to Android Police, Xiaomi's current President Lin Bin and Global Vice President Hugo Barra will be present at the event.
Also, if a Xiaomi PR representative's words (via Android Police) are to be believed, the company will definitely not launch any device.
"We can also confirm that Xiaomi will not be launching in the US or entering the US market this time, but this is an opportunity to get to know the company and leadership a bit more," said Xiaomi's PR representative.
