If Nintendo does make another Wii Pokemon game I think they should have Shadow Pokemon and Cipher in it. They'd have trainers all over the world trying to purify all Shadow Pokemon that Cipher get their hands on. It might get confusing with a whole bunch of people playing it on Wi-Fi and defeating all of the Cipher Admins before other people do but I'm sure that Nintendo could work something out. I really liked the idea of Cipher (who make Team Rocket, Magma, Galactic, and Aqua look pathetic) and how they hardened their Pokemon's emotions to the point where they have none. They add so much depth to the stories of the games they're in and with Wi-Fi, it's sure to be really successful.
