Although so far, only Sprint and Verizon have confirmed they will be carrying the HTC One Max, we have some leaked press shots of the AT&T (and Verizon) version. Above is the new AT&T version directly from @evleaks, and below is the VZW version from them as well.
It is likely the devices will be announced very soon for all three of these vendors, and their on contract pricing is expected to range between $200 and $300 depending on the carrier and the specific deals they offer. Sound off if you are excited to check out this enormous HTC One variant.
