This is the Vax 77 - a MIDI keyboard which folds in half, weighs 25lbs, is made of unobtanium powder coated Magnesium alloy and has two OLED screens (with a rumoured upgrade to a small polytouch screen). It's 77 keys because that's the most they could fit in and still make it small enough (when folded in half) to fit in an overhead locker. But, but, but, there's no price yet, and their site is just a bunch of renders. The most interesting suggestion for synth geeks is that the keyboard will have polyphonic aftertouch - the semi-legendary feature where each key can be pushed harder after the initial attack to control the filter (or whatever) of that individual note. It's the first time any manufacture has offered poly aftertouch for years. Synth designer John Bowen says in this thread and this one that there's nobody making a mass-market PA keyboard, so the Vax will have to be custom manufactured (rather than churned out in China) so expect costs to be somewhere between $$$$ and $$$$$. Still, it does fold in half...
