You're also right that just because a Pokemon mega evolves (like Sableye, Audino, or Mawile) doesn't mean it or it's mega has to have a full art. Again it all goes to a matter of opinion on what Pokemon 'deserves' it.
All of MegaPokémon and its "pre-evolution", will be EX if nothing changes (something like half-art).
For me it's a shame that not all Megas and their "pres" will have FA version, because some, will come in boxes or are in previous sets. I want MegaVenusaur EX FA, Absol EX FA, for example.
I hope someday the secrets cards in some new set, will be FA of previous EX and Megas that hasn't FA.
