Wolf - 85%
There is some reason why Wolf could be cut from the roster. Firstly, Star Fox didn't really need three representatives in the first place. The series has suffered a hiatus up until this year with Star Fox 64 3D. However, according to what users on this forum have said (I have no source), Nintendo may not pursue the series further if Star Fox 64 3D doesn't perform well sales-wise. In addition, although he and Luigi are by far the least clonish "semi-clones" in the series, he is a semi-clone nevertheless. IMO, it also doesn't help that Wolf was the last character added to Brawl's roster before they had to rush Sonic in - IMO, this shows that Wolf may really have just been intended as roster buff, albeit well-done roster buff.
However, Wolf is a popular character, and since we allow Mother to have two characters, I don't see why we can allow a third Star Fox rep. So I doubt Wolf is going.
Wolf is my fourth main behind Luigi, Lucas, and Toon Link, and I'd like him to stay. However, I can't say he deserves to be in SSB4 - he should be in it, but it's not necessary when it comes down to it. Nevertheless, Wolf is wanted (4)
Phoenix Wright - 15%
Phoenix Wright's series has become one of the bigger continuing franchises at Capcom, and his confirmation for Marvel Vs. Capcom 3 helps his chances, since it would provide the SSB4 developers something to work with. Capcom's supposed abandoning of Megaman may (or may not) hurt Megaman's chances, which could make Phoenix Wright somewhat more likely.
However, Megaman should get in before any other Capcom rep. To add Phoenix Wright without adding Megaman first would be a slap-in-the-face to Megaman supporters, and Megaman is by far the most wanted and most deserving new third-party rep for SSB4. In addition, I don't see where the support for Phoenix Wright comes in.
I do think Wright's chances are a little underrated considering his MvC3 appearance, but I doubt he would get in over Megaman or even Ryu.
On the topic of third-parties, I'm mostly neutral on character additions with some exceptions. Phoenix Wright isn't an exception. I'm neutral (3) on him just as I'm neutral on Megaman or most third-party characters, including Snake and Sonic.
