I would envision a massive complication to this involves a great deal of the cosmetics from the Japanese side of pso2 sales things which were exclusive to collaborations, promotional events, and events which no longer exist. The example I can think of is that the Dragon Hunter Frontier Z cooperation where I can imagine the clothes and weapons could unquestionably be given a visual update alongside everything else but that I do not exactly know how the licensing or the way the legal side of the collaboration works where I would wish it had been as simple as Sega going through and upgrading the assets but I do not know about just how much Capcom is involved in that procedure.

The same applies to collaborations like the Final Fantasy XIV cooperation with Odin (which exists as far as I know) where I do not understand just how much Square Enix is involved in that for Sega to be able to update assets . When it was purely just Phantasy Star-related items (such as character outfits, cameos from different games, or other Sega-related properties) I could imagine this likely would have been achieved, or would be carried out. But from the worldwide variant we already don't have the presence of Cougar NX therefore I do not know if there are additional complications seeing Sega's properties that might also contribute to not upgrading everything they could within reason.

I can imagine that likely out there we'll still see somebody wearing those old collaboration things even when they aren't rigged up to the very same criteria as new cosmetics in a similar way and that there would have been outrage when it was made unusable or obsolete. Collabs that have had their cosmetics removed still have their resources exist on the sport so those will probably still be accessible for jp players.

Only improvements we will probably see is the brand new engine enhancing shadows, reflections, colors, particle effects and projecting them from the drapes. You can take a look how just applying better shadows and colours can improve old equipment by checking ReShade screenshots.

The next step after Plains of Eidolon, to cheap Phantasy Star Online 2 Meseta me, personally would have been Dragon's Dogma Online's receptive fields.
