That is exactly what they're going to do. Give us an even (unnecessarily) smaller Mac Mini.
Bad idea. Too small and light, and, it would be an Apple TV and be pulled off the table by its cables, and, not have enough room for all the connectors it needs. It is just right the way it is right now.
With an A8 in it.
Now, that could be a great idea if third party S/W developers could get on board.
Because, well, it'll save them money.
Not sure how super-small saves money.
