Well, assuming that they go with the average each week (3) that means that, with roughly 10 weeks remaining, that means there's 30 more total, leading to a launch roster of 32 (hey, look at that, it's my speculation number!) That said, if they never do less than 3 and do a couple weeks with 4, there's a decent shot of no cuts. For the time being I'm gonna assume they're gonna go with the average. Meaning with the roster we know (assuming Beavers as one fighter and that Vlad is playable for a total of 12 newcomers; and assuming Hugh is returning due to PapaGenos) would make for a total of 5 cuts if my math is correct.
I think the only ones I'm truly 100% against losing are Oblina and CatDog, solely because I want their shows to stick around on the roster. Oblina for being a creative pick and CatDog because of the iconic status.
I'd also rather keep Toph so we can rep the 4 nations. Same with Mikey and Leo for to rep all four turtles.
PTM was funny and is the Captain Falcon equivalent imo, you kinda need him.
