If Anamanaguchi reinvented Chiptune by melding it seamlessly with a Rock band, aivi & surasshu can certainly be attributed with reinventing it again.
It's one thing to mix 8 bit sounds with other sounds. Plenty of artists have done this over the years, myself included. It's really nothing special in itself. These artists stand out because they made something truly amazing that stands on its own, regardless of how it was made.
Also, there's a cover of Lonely Rolling Star, so bonus points there.
