-I've seen it before. Pretty much because alot of People were Expecting Shadow as an echo and were very Surprised he was an Assist when it seemed like he had everything going for him as an echo, there was a Reasoning made that Sega doesn't want another Character overshadowing Sonic as a Playable character, and that's why we didn't get another one
There's no Definitive Source for it, when it comes to that idea and Smash
-I do Think Tails, Knuckles, and Shadow will take Some things from Sonic, but I think at the Most they be Semi-clones, not Compete Echoes. In terms of Smash, all 3 characters would have their unique moves and Abilities and that requires different balancing toward the rest of the Cast, instead of just against the Parent Fighter, which is main Reasons Echoes are Echoes, that they can be jusy Balanced against the Rest of the Cast
-You're right on that one. I guess the whole point is that Nintendo will know Sonic will be very Relevant when the FP2 is going through it's Lifecycle, and that is a Plus when considering another Sonic character being in the Pass
Shadow would have been dope. I can see them using sonic as base, and then using assets from mewtwo for animations. Mewtwo down smash is just one of shadows moves from sonic battle. Shadow feels like a missed opportunity but it's just wishful thinking.
You don't have to Talk like Shadow is Dead in terms of Likelihood
Shadow has always been Overshadowed in terms of Smash Speculation.
-Smash 4, While very Popular with the Casuals on Miiverse and Twitter and youtube, Tails and Knuckles Dominated discussion on More Hardcore sites like here and such, Especilly after Shadow got Confirmed as an Assist Again during an E3 Demo.
-Same deal with The Ballot and DLC around here since Shadow was an Assist
-Shadow blew up during Ultimate Speculation, but it was as Speculation of Being an Echo, where he would be in Sonic's Shadow Moveset wise, there by being Overshadowed by Sonic in terms of Moveset
-Going into Post-Assist Confirmation, Shadow, and Another Sonic Character in general has been Overshadowed even when just talking about Another Sega Character Joining, up until Sephiroth got Confirmed Days ago
-Even with this though, Shadow (& Knuckles) will be Overshadowed by Eggman and Tails in terms of Another Sonic Character being in the Pass, because Shadow is an Assist, and is also Seen alot of the time as Only Echo Material
-With the Idea of an Assist Promotion being possible or happening in this pass, Shadow is Overshadowed by Waluigi, and Also Isaac for the Idea.
With that being Said, That doesn't mean Shadow is Impossible or Dead, Shadow I don't think will ever be seen as Likely option in Speculation (as an unique Character) until he actually gets into the Roster. Now A lot of the characters, including the Recently revealed Sephiroth was Not seen as likely option or Alive until they got into the game as well. I will just say don't let the Common Smahs Speculation dictate all your views. This doesn't mean Shadow will actually get in, but you don't have to count him out either
