Hm... I dunno. Hyper Sonic is the next step up from Super Sonic.

But I do believe that when the Chaos Emeralds turned into Hyper Emeralds for the first time, they changed size and shape (either they were old single or step cut as seen in the classic era into round brilliant cut in the modern era), but once the Hyper Emeralds reverted as the Chaos Emeralds, they merely changed size but retained the round brilliant shape.

Still Super Sonic is ment to be Sonic's trump card if things go sour and Super Sonic is able to take down gods. It's hard to imagine Hyper Sonic for modern gameplay as well as what it's purpose would be.
