From the WindowsCentral sneak peek:

If you're a fan of Windows 10 Mobile's Continuum, we've got some good news for you. Alongside teasing a new Elite x3 at Mobile World Congress, HP also teased a new Lap Dock for Continuum, with a slightly bigger screen and an overall more "equipped" device.

Much like the new Elite x3, we know basically nothing about the new Lap Dock. Judging by what we've seen, it appears to be a 14" device rather than 10" like the first generation Lap Dock. It also has a much larger keyboard, and a trackpad with dedicated left and right buttons. It also has full size USB ports, instead of USB-C ports like the current Lap Dock does...

...HP is keeping tight-lipped over their future Windows 10 Mobile plans, but it's clear that HP are dedicated to their Windows 10 Mobile line of devices. Stay tuned to Windows Central for more.
