According to the original rumor, the last bit of info confirms that Tails will be playable. Not only that, Metal Sonic would be the main villain. I guess there was something to that marketing for Sonic CD. Reading the info that the source gave, it seems the version he got was pretty early and sections of it weren’t completed yet.
“You can select either Sonic or Tails before loading the first stage, but selecting Tails simply grants you playing as Sonic with a Tails life icon and ‘Tails got through Act X’ messages.”
“The level design consists of many bottomless pit areas and failing to avoid Metal Sonic after he teleports usually results in death.“
I’ll be publishing the full e-mail later tonight for the interested. This seems like a given, at least to me. After Sonic CD coming out ‘before’ they announced this? I pretty much knew it was going to have Metal Sonic. Tails was a given because he was introduced in Sonic 2, so introducing him in Episode 2 makes sense. Like you can assume that Knuckles will be in 3.Ad:
