The One X+ made it out of the gate, but there was no sight or sound of the One VX. Either it was left at the stable or something else was afoot. Unfortunately, no word was forthcoming from AT&T as to what happened. However, a spokesperson informed the folks over at Android Central that all channels (stores, agents, online) will be fully stocked by December 7th.
We could speculate on all sorts of reasons, but rather than throw every theory at the wall to see what sticks, we will take the high-road of hope and hypothesize that the delay was to ensure the handset delivered with Android 4.1 or 4.2 Jelly Bean. This is, of course, just speculation. The real reason for the delay is probably due to a far more practical issue, like supplier hold-ups. So, do not hold us to it.
Spec-wise, there are certainly some features that position the One VX as a middle-of-the-road Android handset. However, if you saw our video hands-on with this device, you would notice that our initial impressions of the handset were pretty positive. Since AT&T has the One X+ priced at $199.99 on a two-year contract, we are eager to learn what the price point of the handsome One VX will be once it is available.
