I never said anything about them being likely, the whole indie list before that and the brief mobile mention were all characters/series I'd be happy to see, nothing more. I know realistically, stuff like Nikke, Pseudoregalia, Signalis, etc have an actual 0 chance and most of the others don't fare much better.
That's pretty surface level and dismissive but I suppose I can't fault you for that considering the marketing. Either way, they're not really a serious consideration. If Mai couldn't get in as a background cameo I don't see any scenario where Nikke, Azure Lane,etc have any real chance.
I would include Granblue in the camp of mobile/gachas with some chance though. Probably still behind Genshin but that's a pretty notable series as well.
