Either way, there's little evidence backing up anyone beyond Erdrick (and even he's mostly an educated guess based on datamined codenames & previous rumors). Steve in Smash wouldn't really be my cup of tea, but I've since grown to not hate him as much (but as I said before, it has more to do with most of my own dreams being snapped out of existence).
Boy, isn't this how I feel? With all these rumors and speculation, I've pretty much realized there's zero chance of any character I care about or want being featured in Smash. The Belmonts were the end of the line, basically.
