bbblp and Sky your both on point, but Sky, Eggman was only originally called Robotnik here, in Japan, he was always "Eggman".
@Josegtx- 60 bucks.
Other than Sonic and Robotnik, definitely keep Team Chaotix, Amy, Metal Sonic and of course, Tails and Knuckles.
Axe Shadow, he was cool in SA2 but after that he got annoying. I think I would've liked Shadow if he weren't neutral/a ****in' anti-hero (one of the most overrated archetypes ever, IMO). They should've given him a strict alignment and made him more like Espio (or Vegeta, I don't mind Shadow being more like him, either), but since we have Espio now, we don't need Shadow anymore.
Burn Silver, Big and Chip and the other hosts of character introduced in the Modern Era.
Rouge I guess could make future appearances because Knuckles only gets the spotlight when she's around. Plus, I really liked her in SA2 when Lani Minella voiced her. Don't put too much emphasis on her, though.
Also, this'll never come true... but I'd love to see Scratch and Grounder make their way into the games.
Also, BRING BACK THE ****ING CHAO GARDEN, SONIC TEAM. I can't stress how fun that was in SA2.
@DCR- Sky Sanctuary looks so amazing in that vid, but dude, have you seen Seaside Hill? It not looks gorgeous, it has elements of Hydrocity Zone, Ocean Palace and Labyrinth Zone in it, too. That's probably going to be my favorite stage other than Speed Highway, City Escape and Chemical Plant.
Lastly, as DLC, I hope they give us Ice Cap Zone from Sonic 3, Metal Harbor from SA2, and Egg Fleet from Heroes.
I may try to get both the 360 and the 3DS versions but I'm really starting to get disappointed with the 3DS version.
@sek- I prefer the ending version:
