The Lenovo Z6 Pro has been official for only 2 days (or since April 23, 2019) now. However, its maker claims to have accumulated about 200,000 'reservations' for the device online in China in 24 hours. These bookings can be made on sites where a device is to be sold, such as JD.com, so as to be sure of getting a unit when a given pre-order event begins.
In the case of the Z6 Pro, this will take place on the morning of April 29, 2019. Accordingly, there is no guarantee that all of Lenovo's apparent reservations will translate into sales. However, it is a valid indication of how popular the device has become. With its Snapdragon 855 processor, alleged "PC-grade" cooling for gaming, quad camera and 12GB RAM variant, this is not much of a wonder.
The aforementioned highest-end SKU - which also has 512GB in storage - will go for RMB 4999 (or about US$745) on April 29. Those less interested in this aspect of the Z6 Pro may prefer the 6/128GB variant (RMB 2889 or about $430), or take a middle ground with the 8/128GB (RMB 2999 or $445) or 8/256GB (RMB 3799 or $545) Lenovo Z6 Pros.
