450 Wh/kg SolidEnergy batteries, the lightest rechargeable cell in the world?

We've seen the claims before, 10x, 5x, 3x the energy density for some new wondrous cells.

Panasonic 18650GA cells have a gravimetric density of 224 Wh/kg allowing some fixed wing drones to achieve 2+ hours of flight, these new SES cells claim 400-500 Wh/kg and are apparently available for sale now.

Could we see a 1 hour multirotor flight as normal soon?
