>>55301420They announced a while ago that they're keeping Bank online afterwards, but that you should transfer stuff up as soon as possible.
I don't see it lasting much longer than a year. There's no real incentive for them to keep it online when they aren't getting sub money anymore and the amount of people that still actively use Bank is probably pretty small at this point since it technically can't get any new users. It's been fine for years but if the other servers going offline fuck up Bank somehow then they have no way to push an update since the eshop closed.
True ribbon masters died with the dex cut anyway. There's such a small handful of mons that can get everything now.
