I'm glad Cloud is in and probably Crash that gives this roster a boost it needed.
We're both lawyers.
Look at this from superbots point of view.
If they say the exact number there is, it will disappoint people when they see x amount of spots left with x + 5 characters wanted.
If they say, we have over 20, then people like us will automatically jump to conclusions saying, ok so there is a max of 29 characters, and then once again, you have the first situation
Also, if they give a vague statement like over twenty, and they have dlc getting planned and possibly hidden characters, then they have to decide if they should include those figures or not?
overall im just saying that there are a lot of things that could go wrong when they make a statment about the roster size, especially in a game where the roster is the most important part. If i were them, i would just stay quiet. It keeps converstation up, and the mystery alive.
