Hi, welcome to our Twitter page. We're here to let you know something big is coming May 30th! Stay tuned... — Essential (@essential) May 25, 2017

Essential will focus on a line up of connected tablets, smartphones and mobile software, according to early reports. The smartphone prototypes are reportedly larger than Apple's iPhone 7 Plus and feature bezel-free sreens and ceramic backings. The reports also say that the Essential team is working on a feature similar to Apple's 3D Touch and magnetic charging capabilities, which seems to position Rubin's new company as iPhone competition rather than other Android-powered hardware. We hope to find out more next week.

Update: A followup tweet reveals a shadowy outline, but with a little editing appears to show a 360-degree camera add-on that's similar to the old Sidekick camera (a previous Rubin project). Looking at a recent tweet of Rubin's appears to confirm the camera, showing a colleague working on some sort of surround camera setup.
