I also think that even if these new remakes of Advance Wars 1+2 do well enough for Nintendo, they will likely greenlight remakes from NDS entries before a new game.
Or maybe they will look foward for a Batallion Wars 1/2 remaster/remake.
We should wait a bit to see what is Nintendo approaching with next Switch iteration. We are already seeing sequels of key 2017/2018 games (Splatoon 3, Zelda BOTW2, M+R2, Mario Party, Triangle Strategy and these week there was rumors of Xenoblade 3) getting announced for 2022. I wouldn’t be surprised if we get a new Mario Kart game announced for next FY (releasing by march 2023).
So, maybe next Smash game will be released a bit sooner than we think? I know that the general rule is one Smash entry per game, but, what if they are planning 2 Nintendo crossover games for Switch? Maybe another genre?
PS: I hoped next Camelot proyect is related to Golden Sun; either a remake/reboot of GBA games, or whatever else.
