If that rumor*** is true, then we MIGHT MIGHT MIGHT get 3 newcomers between December 1 and December 15
The Rumor is actually pretty good:
The Number of Newcomers (With the Challenger Approaching Banner)
August-3 (Ike, Pokemon Trainer, Diddy Kong)
September-0
October-3 (Sonic, Dedede, Lucas)
November-0 (So Far, It looks like none)
If December were to reveal the entire starting roster, it would bring it to 25 total characters, exact amount in Melee:
THIS IS JUST AN EXAMPLE:
December-3 (Ridley, Krystal, Ashley)
