Xiaomi's Redmi Pro 2 isn't official even now, and maybe that's never going to change. A new rumor out of China today claims that the Redmi Pro 2 has in fact been canceled by Xiaomi.
It will be replaced in the company's lineup by a phone that's to be called Xiaomi X1. This will have two main hardware versions - one with a near-bezelless display, the other with a normal panel.
Update: As it turns out the X1 and Redmi Pro 2 are actually different devices so there's a chance we'll see both.
The former is supposedly coming with a 5.5-inch screen with 2,160x1,080 resolution, and the Snapdragon 660 chip at the helm. On the rear we'll get a dual camera system with Sony's IMX362 or IMX386 sensors, under which we'll find a fingerprint sensor. The hole for this is portrayed neatly in the image above, which allegedly shows a case for the upcoming X1.
The handset will retain the 3.5 mm headset jack. It will start at CNY 1,999 ($294) with 4GB of RAM and 64GB of storage, and go up to CNY 2,499 ($368) with 6GB of RAM and 128GB of storage. These are probably the prices for the 'regular screen' version. The bezelless iteration is likely to pair 6GB of RAM with 64GB of storage for CNY 2,299 ($339), and 6GB of RAM with 128GB of storage for CNY 2,799 ($412).
The Xiaomi X1 is said to arrive by the end of this month, alongside the Mi 6 Plus and MIUI 9. Do however note that it's entirely plausible that "X1" is in fact just Xiaomi's internal codename for the Redmi Pro 2, or, for that matter, a device to be sold under any other name.
