Honestly saying im a bit lost on 'our notes' release date, as almost all of the cards were shown, and a lot of new features were added into the game, i do feel like it will release way sooner.
for now, we have full card sets for each band, except for yumemita, but i think that the cards will be posted as anime progresses, so to not spoiler some important parts with them. so far, from yumemita we have only have ritsu SP card (honestly i thought that there was arale one too, but i didnt find it. im gonna recheck just in case. okay, rechecked, no arale card nor other members)
so, lets say ymmt cards will come out as anim progresses, that means (counting todays 6th ep release) in about 6 weeks, that means that on 10th of september last ep will air, and safe to assume that cards will be out too.
so, i do think that maybe, the game will come out sooner. my best guess is 30th of sept/early in october, but thats just random dates!! im nit saying that it will come out!!
okay, let me also explain the date!! 30th is when both millsage and dumbrock singles r coming out!! well, we already got them, but they will release as physical merch!! (i think.) now, i think it would be cool to release both game and single on the same day, so this date is just a personal random want!!
now, why i think it could be in december!! (hope it wont be actually) well, most know, but millsage and dumbrock will have their first lives in december!! and, they r VERY close to date release. so, i think it could be better to first release the game to get to know characters and stuff, it also will gain more fans, and a bigger chance for people to come to their lives. also its christmas time and right before new year so uh. they dont want a christmas event on the date of release right.
i think thats about all!! at the end it rly stopped making sence so im sorry for that!!
