Android Central​Update: Nothing to see here, folks -- turns Moto's just "engaging with Facebook fans." We'll have to wait awhile longer for our RAZR HD fix. (thanks @ChloeAlbanesius)

Original: Today Motorola's taken to Facebook to tease what seems to be an upcoming smartphone, and it's promising an "big reveal" before the end of the week.

Motorola says, "We'll give a clue each day all week and make the big reveal on Friday." The first clue states that the phone has "the power of 4G LTE," which doesn't give too much away. Of course, it's possible that Moto's just engaging in Facebook banter with its fans, but to us this bears the hallmark of pre-release hype.

We've seen plenty of (Droid) RAZR HD leakage over the past month or so. The device has shown up at the FCC, as well as in a series of leaked images, some of which bear Verizon's 4G LTE branding. From what we can tell, the RAZR HD looks like a cross between the Atrix HD and last year's RAZR MAXX, with the former's 720p display and on-screen buttons, and the latter's chassis style and kevlar back panel.

We'll be watching closely later this week for the eventual reveal. Moto fans, are you hoping for a RAZR successor on Verizon this fall? Let us know down in the comments.
