Yeah, ok!
And why should Dawn or May have priority over Misty? Neither of them comes before the other and each of them are irrelevant now. Just because they didn't win their princess pageants doesn't mean that they deserve an episode to commemorate them when they do.
Well I don't know about Dawn, but back in the AG era May was so tremendously popular compared to Misty that nobody could have possibly been oblivious to it.
As I said, I always assumed Misty's departure wasn't intended to be permanent at first, it only became that way due to the success of the Contests and how incredibly popular May became in such a short time.
Then once that worked, the writers then decided to bring in a new female protagonist every region. Again with Dawn it worked, and while Contests seem to be on their way out, Iris looks refreshing on her own.
