He wouldn't even need all seven to get the job done. Chaos Control can create time portals for decades long journeys with just two emeralds.

I'm hoping the story would be about Time Stones. In Sonic CD which Generations prooves major event to canon, regardless of good or bad ending, Dr. Eggman gets away with one of the Time Stones and thats the last we see of it. It never shows if this has had any consequences to Little Planet, but we know Dr. Eggman eventually turns the planet into Death Egg mk.II which isn't entirely destroyed at the end of Sonic 4.

So Eggman has a planetoid size time machine stored somewhere since before Sonic Adventure. Unless there will be a "Sonic the Hedgehog 4: Episode 3", Eggman doesn't have a reason nor an excuse to build another.

But chances are he'll just make an emerald powered time machine or something.
