Just like CES itself, Alcatel is only just getting started. In addition to the 5-inch 720p Scribe HD that was just announced, there's also going to be a Scribe X version of that handset with a top-end 1080p panel, a slightly faster 1.4GHz quad-core processor and a higher-res 12-megapixel rear camera. Separately, there'll also be an LTE version of the Scribe HD, which we gather will have much the same specs except for the faster modem. So, the crucial upgrade options are there, just not at the same time.
