HTC EVO 4G LTE 2
One of the best Android smartphones of the year was the yearly HTC EVO release for Sprint's network. This year's HTC EVO, the HTC EVO 4G LTE, was the first to have 4G LTE support and while Sprint's 4G LTE network is small now, the sequel will benefit from a much larger network in 2013.
Nothing is known about a potential EVO 4G LTE 2, but given HTC's progress with the EVO 4G LTE and One X, expect a quality display, solid camera, and a thin design. We've also seen HTC make strides in the battery and storage space arenas as well so it could be that the EVO 4G LTE 2 could feature the whole package.
Release Date: Unknown, likely mid-2013.
