Eris is 27% more massive than Pluto. It even has one known moon. You can't have just 9 planets. It's either 8 or 10+.

Eris is 27% more massive than dwarf planet Pluto, though Pluto is slightly larger by volume. From it's orbit, Eris would be #10.

My point was: we can't go back to exactly 9 planets. You'd be hard-pressed to write a criteria that includes Pluto without including Eris... And frankly, we'll probably find several even larger trans-Neptunian planetoids, in time.
