Of course more people will become active in the speculation once more information about Smash 4 is revealed, however, from the people that have voiced their opinion in regards to Smash 4, most people want a Mario newcomer, but seem to disagree with the other choices people bring up. Toad has the most support of all the Mario characters, however, as you saw in this thread, there is many who feel he is too "bland" and too much of a side-character in the Mario platformers to warrant playable inclusion.
Toad does seem kind've bland, imo. If he is included I can see him getting a couple of brand new moves to make him interesting. Like Peach, I think he would also have the turnips and maybe for his upB the magic carpet from SML 2.
I think the Mario character pool includes Bowser Jr., Rosalina, Toad,>>>>>>>>Daisy>>>>>>>>>>>>Waluigi
Yeah. I have noticed that too. Lip also has a much stronger level of support on GameFAQs than other places that allow Smash 4 discussion.
I wouldn't mind Lip, I think she is also a good candidate for a remodel like Pit if she was included.
