Note: These articles are more for discussion purposes before E3. They'll be short, sweet, and to the point for a brief recap and looking into possible characters/stages for each series in Smash Bros. These also go by a "Don't expect too much" philosophy. Please remember to be civil in the comments discussion.
Smash has a history of introducing one-off characters from smaller franchise and to finish this off, we haven't quite covered new franchises yet, but there are plenty of other new characters to look into!
Doesn't really exist for this.
New CharactersThere's quite a few other franchises to look out for. Code Name S.T.E.A.M. seems like a smart choice at first, though it doesn't actually offer much to work with - much of its cast consists of historical figures and public domain characters. Isaac from Golden Sun, and Ray 01 from Custom Robo are fan favorites to make it in. An ARMs character is definitely plausible, and Dillon from the Dillon's Rolling Western games is also not impossible. Beyond that, it really comes down to what Nintendo wants to promote and what the team finds interesting.
For retro characters, it's a bit more difficult to pin down, but Takamaru, Mach Rider, Excitebiker, and Balloon Fighter all seem like good candidates, if we see any.
Any new stages with no character don't feel likely but it's hard to tell.
Any new characters that get added for their own franchises will probably get their own stages.
