My Predictions:
DUH
SFV
MKX
UMvC3
Sm4sh
ZUH?
USF4 - Even with SFV taking over, I believe there is still enough interest and playerbase to show up for the game that essentially lit a fire underneath the FGC's ass. It won't be going anywhere.
GGXrd Revelator - Guilty Gear brings in larger US attendance compared to other anime games with nearly 1000 entrants last year, and really, when you have the most infamous fuckup from last year under your belt, a return would be expected, if not demanded.
Melee - If it wasn't for Melee, Sm4sh may not have even been considered. Plus, it's still the main event at a lot of Smash community events, and it has a larger playerbase then Sm4sh that shows up to these majors, even though it has been considerably neck and neck as of late. PLUS, It's Melee's 15th anniversary, not like that really matters.
KI - Not the strongest game, especially nowadays, but it has its fans, and a Season 3 in progress. Probably one more reasonable year left.
That's the certain titles for me. As for the rest of last year...
BUH?
P4AU - The game at this point just isn't relevant anymore considering there's a better chance of another version with P5 characters included being released on console than there is of the console version getting the 2.00 update.
Tekken 7 :Fated Retribution - Really hard to say. I'm sure Namco Bandai/Markman want it on the docket, but I would not be surprised if Pokken Tournament is favored, since it's the 20th Anniversary of the Pokemon franchise, and it's actually on console despite being a pain in the ass to set up for local play. Hasn't stopped Gundam Full Boost from happening.
