EVLeaks has proven to be fairly reliable over the years and his latest prediction is that the next Motorola Moto X will be called the Moto X+1.
We haven't seen too many rumours surrounding this upcoming device so we'll have to wait and see what the Lenovo owned unit will deliver. It is important to remember that many Android watchers still call the Moto X the best Android phone around (even though it was released August 2013).
In Canada the Moto X was released exclusively on Rogers and I am really hoping they bring the new device to Telus and Bell also.
In the US and Canada, we have seen more and more tier-2 carriers selling the Moto X which typically indicates it will shortly be replaced.
