@Mario_And_Sonic_Guy: No, that would be four. Pokemon Trainer adds two more characters then it would with just one Pokemon, not three. Sheik and Zero Suit Samus add two. Therefore, in that case, 54 would be the most we can realistically expect. Remember, Brawl has 39 including transformations and 35 slots.
Okay, so it's been established that most of us don't want the same roster for both games so rather then try to panic about the possibility of that happening, let's try to discuss how likely this actually is.
So that leaves me with a question. On a scale from 0 (Impossible) to 10 (Guarantee), how likely do you think it is for us to have to deal with the same roster for both verions?
My answer is 2. There is no reason for Sakurai and his crew to do this as all it will do is discourage potential fans from buying the game and that it will scare away millions of fans, especially if the roster goes below the 40 character slots limit. As such, this maneuver will cost them millions of dollars they would have gotten by keeping the roster at 25-35 slots and the 3DS version at 44 or more. Because of this, Sakurai is aware of the consequences that awaits his team and as such, will likely take the more profitable route of these two:
- All characters not on the 3DS version will be exclusive to the Wii-U version.
- Lots of exclusives on both sides.
Both will please fans and they have more benefits then negative consequences for both sides. There's no good reason for Sora Ltd. to do this to us. Unfortunately, I have a huge gut feeling this could very well happen.
Let's try to discuss the (unfortunate) possibility of this and let's not try to panic over this again (Like I admittedly did).
