Tyler, you seem to be in luck since Rival Destinies is premiering in Australia next week so definitely try and watch all the episodes if you can. I watched several of the episodes already via an online source.
But as Aaron said, definitely watch it if you want to find the right time to watch the series again.
I would also like to get back into the Anime, I started watching the DP series and then stopped about 20 episodes in. Unfortunately I don't really know how to keep track on when new episodes air over here.
