If they are doing Namco characters, then obviously they must include Yuri Lowell(Or Lloyd Irving). But yeah, I hope that they get rid of 2/3 Starfox characters(Preferably Falco and Wolf), Ice Climbers, Jiggly Puff, 1/2 Mother characters(preferably Lucas) and Lucario. I think Dedede, Ganondorf, Yoshi, Donkey Kong, Bowser, and Pokemon Trainer could stand to be shown the door in favor of rotations. (Pokemon Trainer could just have a Pokemon swap)
So I think those 12 should be swapped out for new characters. As for replacements, I would like to see:
1. Yuri Lowell(Tales of Vesperia)
2. Bisharp (Pokemon)
3. Haxorus (Pokemon)
4. Lloyd Irving (Tales of Symphonia)
5. Knuckles (Sonic)
6. Professor Layton (Professor Layton)
7. Megaman (Megaman)
8. Yarn Yoshi (Yoshi's Epic Yarn?)
9. Tom Nook (Animal Crossing)
10. The Shadow Triad (Pokemon)
11. Dingo (The animal. No affiliation with any sort of game)
12. Pokemon Trainer Team Swap (Krookodile, Flaffy, Scyther)
