It looks like ASUS is gearing up to launch a successor to the ZenBook Flip sometime in the second quarter of 2017 with the ZenFlip UX370. The information comes from leaked product plans reported by Italian blog Notebook Italia, but includes no technical information or specs about the device.
What makes this leak particularly interesting is that this is the first time ASUS is employing the ZenFlip name on any of its products. It's not out of the realm of possibility to assume the ZenFlip UX370 will just be an updated version of the ZenBook Flip UX360, simply with the line adopting a truncated name going forward. Curiously, the ZenBook Flip UX360 itself was only updated with Kaby Lake chips in September of 2016.
As for the ZenFlip UX370's specs, we'll have to see what ASUS has in store. With Mobile World Congress (MWC) on the horizon, it's possible we might get a close look at the ZenFlip, along with the other products on the slide (including that mystery gaming product), at the end of February.
