LG teased a slide-out phone in the Wing announcement and no one noticed - Android Police

The pre-recorded event was over an hour in length, so it's not too surprising that a teaser for a new slide-out device at the very end went unnoticed by most people.

There's very little detail visible, so it's not clear if the section sliding out is a keyboard (perhaps for people mourning the death of TCL's BlackBerry-branded phones), a covered display, or something else entirely.

I'm guessing an Xperia Play-style gamepad is off the table, given there's very little clearance between the sliding component and the outer shell.
