I'd say the only thing it's a newish aesthetic for is web UI that isn't implemented in Flash, but even then there's been periodic resurgences. Command and Conquer, Starcraft 2, I'm sure there are tons of examples I'm unaware of.

The only recent novel addition—I'd speculate—is the specific influence of Cyberpunk the game with its shiny surfaces and pink highlights, but even then it's hardly new.
