You know, in regards to ballot picks, I seriously think we are getting 4, and that they won't be Veterans. My reasoning is that if they are going to all this trouble of collecting a ton of data from different regions, they will want them all to be new fresh and exciting, so that rules out Vets due to being in previous games. The other tact thing is they don't want any region to feel left out, of the main 3 NA, EU, and JP/Asia, which is why each has a different submission setup, to guarantee votes from that region. So, we get one from each region, and a global pick. Note, this still isn't a popularity contest, the amount of support is a factor, but so is the character's potential, being from an unrepped/repped franchise, and legal matters, the latter of which makes Nintendo owned characters most likely. The final aspect of this, is that I expect at least 1 to be from an unrepresented franchise.
Now, before you get into a huff about me saying no vets, I'm saying no vets as part of the ballot. I'm still thinking Wolf is extremely likely for August, and while I believe at least one if not several ballot picks are already in development(Even if they didn't start finalizing until halfway through a handful of obvious front runners have at least their concept work done), and I wouldn't be surprised to see one released for the end. Heck, I think the *Mario* slots could be the last two vets, and/or the last 2 pre-ballot picks since they are most likely at least 75% done, and were being codeveloped and balanced alongside Ryu, Roy, and Lucas to speed up the process.
But hey, that's my theory
