No, but a lot of people think so because of the "two slots" left in the roster, and because the Wii U roster can only fit two more characters, plus there's enough room for two more characters on certain views of the website's character list you see at the bottom of various pages.
Its all just a series of coincidences, though.
No, it doesn't. They could've just as easily threw in a random number of extra slots because they knew they had more characters they wanted to do, but didn't know how many.
Personally I think we're getting 3-5, probably 4.
......ok I feel you missunderstood quite hard here.
I said that 2 unused slots were found.
This means that they would intend to AT LEAST do 2 because otherwise, I HARDLY think they only intended one.....seriously, even without the slots, I would hardly believe that, but with the slots....I have no reasons to think that.
So what you are trying to tell me is they could have put an intentionally overkill amount of slots and yet.....the only chance it would happen is if they put only 1 character hence why I think it is safe to assume it means at least (not equal) to 2.
Seriously you replied like I was saying that it means 2 and only 2, no I meant AT LEAST 2.
I even told I believed that 2-3 were the msot likely and 4 for me starts to be unlikely!
