Though Motorola has told us that their next flagship will be official in late summer, it looks like they’re getting ready for it a bit early. A link to a Motorola website contains a placeholder for an AT&T variant of the possibly upcoming “Moto X+1″ — though pricing and other critical details like design have not been revealed yet, this new leak looks to possibly confirm the name of the device, and other MotoMaker-related information.
As the image above shows, we have seen the “Moto X+1 for AT&T” name pop up. Droid Life says they have found references to Sprint and Verizon on Motorola cached pages as well, though T-Mobile is nowhere to be seen at this point.
As far as leather backs through MotoMaker go, remember that @evleaks first brought the possibility in a Tweet a few weeks back. The Droid Life report states that they are seeing black, blue, grey, and red leather options in MotoMaker, which the device will almost certainly be customized through.
Though we cannot say for certain that this information does indeed correspond to the Moto X+1 (or whatever it ends up being called), but at least the leaks train has started rolling.
Update: It looks like the Motorola page has been taken down, folks, as of 8:50 PM ET. Although, we did discover the previously mentioned Verizon and Sprint references on this sitemap page, which still looks to be showing links to (though they are dead now) the phone for those carriers.
