The Chinese website known as Weibo, leaked out a list of 2018 devices that will allegedly be powered by Qualcomm's Snapdragon 845 chipset. The list is quite interesting as it gives the names of the unannounced smartphone successors of 2018. Not only that, it also gives the months that the device will be announced too.
The list is translated as follows:
February - Samsung Galaxy S9/S9+, LG G7/G7+
April - Xiaomi Mi 7
May - HTC U12+
June - OnePlus 6, Sony Xperia XZ Pro-A, ZTE nubia Z18
August - Nokia 10
September - Samsung Galaxy Note 9, LG V40, Xiaomi Mi MIX 3
October - Google Pixel 3 (and XL), Sony Xperia XZ2, HTC U12+, ZTE nubia Z18S
November - Moto Z 2019
December - OnePlus 6T, Samsung W2019 (this is a flip phone)
It is interesting to see Motorola pushing their announcement date back to November, as they have been announcing their Z flagships in the summer. The rest of the list seems to fall in line with the release schedules we've seen the last few years. As always with leaks, take this one with a pinch of salt since this is not confirmed information.
