2. No. 2: The Environmentalist

This polished concept isn’t a million miles away from the 2009 PS3 Slim redesign. Eco-friendliness is the idea: the case is built from 60 percent recyclable materials, uses zero watts in standby, and can save game progress using its “ECO Restart” function. But the awkward diagonal disc slot might be an issue in tight spaces.

Designer: Joseph Dumary
