Yes, I'm currently attempting to get all the Eeveelutions. I currently have 2 Eevee, a Jolteon, a Flareon, a Vaporeon, an Umbreon, a Glaceon, and a Leafeon. All I need now if for one of my Eevee to become an Espeon and I'll be finished. Like many other Pokemon I'm currently raising, I will send them over to Platinum after I get it on the 22nd.
I've already completed my Pokedex, so I don't have anything else to do after I get Platinum.
