Has anyone asked ASW how many characters they are targeting for release? Don't think I've seen any interviewers ask that yet lol.
Yes, but Tomoko Hikori (the game's producer) evaded the question.
"Q: How many characters will be in the game?
A: I can't say right now... but we can't just have so many characters in fighting game. So we will decide on who will be fun to play, as well as the character's popularity in Dragonball."
However, you could read a little into her answer here, as she went out of her way to draw a connection between the current roster size and how complete the game is, and potentially get a rough idea of how large the cast will be...
"Q: What is the game's development status?
A: We only have 6 characters shown, so hard to say... About 20% overall?"
This puts the ceiling at 30 characters. Though I think many of us suspect we won't get that many characters (mid twenties seems far more likely).
So If they Go for the old formula, the First game Will have 13-17 characters and the Second 21/25
I absolutely see where you are coming from, and I would be okay with those numbers usually, but they are going to receive some fairly heavy criticism if they try to make a 3v3 fighting game and the initial roster has less than 20 characters.
