>>92643639I disagree, EN5 will not happen until late 2025.
And I'm betting they are going for a more musical look like they did with the last two as well as the new found popularity of Girls bands in the US with animes such as Bocchi (You have to recall Japan is always late to cash in trends) the question is what theme they would select for this new generation as we have to also remember that Cover always has the general vision of the generation first and then they scout the talent to see if they are fit for said generation.
For what theme they could choose? Maybe something like American Pop or maybe some executive is obssessed with the punk-goth astethic thanks the "It's not a phase" and wants a more rock-punk theme.
Definitely the hardest part to predict.
