HTC shared plans to live stream their HTC One M9 press event before Mobile World Congress on their own at 7AM PT on March 1st. HTC will stream the event from their own website as they unveil the HTC One M9 and some other "surprises."
In fact, HTC's Jeff Gordon claimed the “best parts of HTC’s March 1st launch event are the parts you have NO IDEA are coming.” Of course, this was a smart PR move considering that practically everything about the HTC One M9 has been already leaked.
