@Evleaks is at it again, this time leaking the info that the successor to the Moto X, now being referred to by the codename Victara, will be sold on all four major U.S. wireless carriers. No info yet on specs or pricing, aside from the (quite possibly fake) pages that were circulating around the interwebs, purportedly from Motorola, listing a sale price of $400. Interestingly, those previous (probably fake) pages made no mention of T-Mobile carrying the X+1/Victara, but apparently that is no longer the case, if it ever was. Come on Moto, the cat's pretty much out of the bag at this point, give us something already!
