The Moto Z may be receiving support for Tango in the future, according to Motorola's CEO Aymar de Lencquesaing. The ability to use Tango technology would be coming to the Moto Z through a Moto Mod attachment as Tango isn't solely based on software, so the device wouldn't simply be able to go through an update and then be Tango compatible. The mod, which is not yet confirmed but is likely, would carry the necessary hardware to enable the Moto Z as a Tango phone thus allowing it to use Tango apps and take advantage of the augmented reality tech.
So far, there is only one Tango phone out on the market, and that's the Lenovo Phab2 Pro that was announced earlier this year and recently launched. While there will likely be more Tango phones in the future, it sort of makes sense that Lenovo might position the Moto Z to be the next device to work with Google's Tango technology. While the hardware inside the phone itself doesn't support Tango, the Moto Mods make it a perfect device for easily attaching the necessary components, and when done users could simply swap out the mod back to another or not use one at all.
While the Moto Mod functionality of the Moto Z does make the phone a great candidate for the Tango camera technology and software, the simple fact that it would be easy to slap on an attachment and enable the phone for Tango is probably not the only reason why Lenovo has been considering developing such a module. As Lencquesaing states, Lenovo is beginning to think of how they as a company can start to bring back products that are "on the fringe." A Tango Moto Mod is likely one such method of realizing this particular goal. Currently there is no detail on when Lenovo might launch a Tango module for the Moto Z, let alone officially announce that it's coming, but the fact that they have acknowledged its probable existence is surely going to be exciting for Moto Z owners, and may even gain the phone some new prospects.
