It's going to be pretty easy to determine who the last two fighters are once we have hindsight. I think you mean insight.Given Lloyd is more then likely to return as a Mii, that can give us hindsight who among the last two fighters are. As mentioned either a sword fighter, Namco character or both in general.
At this point I just can't see Lloyd being picked when all the other Sm4sh Miis have returned and that's the only one yet to not return.
But I also think you're connecting dots just to connect them. Lloyd doesn't have to show up with a character that's anything like him. Gil showed up with Steve.
I don't recall this being the case. There were probably a few people who believed the AT replaced the costume, but I think most people just figured it would arrive later, which it did. It seems preferable for all involved to release third-party costumes as DLC, so Akira also being an AT didn't convince people the costume wasn't going to eventually return.One thing about returning miis which is interesting to me is the case of Akira. Akira was revealed to have an assist in the base game, and when Joker came and went without Akira getting his costume back (he's Sega owned), most thought that was the end of it. Weirdly enough, though, his mii came back despite him having a brand new AT.
Truthfully I don't think we talked about it all that much since very few seemed to care about Akira, lol.
