I can imagine that likely out there we will still see someone wearing those older collaboration things even if they aren't awakened to the very same standards as fresh makeup in Phantasy Star Online 2 Meseta
a similar way and that there would have been outrage when it had been made unusable or obsolete. Collabs that have had their makeup removed nevertheless have their assets exist on the sport so those will probably still be available for jp players.
Only improvements we will likely see is the new engine enhancing shadows, reflections, colors, particle effects and casting them against the drapes. You can take a look how exactly implementing better shadows and colours can enhance older equipment by assessing ReShade screenshots.

The next step following Plains of Eidolon, to me, personally would have been Dragon's Dogma Online's open fields.
SEA peep here. Not actually play PSO2SEA but I did play A LOT of games in SEA release. Maintaining service by means of a localizer (distributor), but backslash of the distributor be able to alter the sport itself or stray afar from the initial maintaining plan from mom company (in this instance SEGA). Many games come and go only as a result of bad maintaining and being exploited. With Sream being a thing since quite a while (actually steam slowly became a very important thing in about PSO2SEA launch, the growth of MOBA such as Dota2 and LoL was a thing), many issues of localizer were turned out, including manipulating value (PSO2, when enemy dealt more dmg and assume to be) to unjust monetization (several, including Garena in exchanging RP rate in local currencies, also for PSO2 was costume items and unite outfit). It all are a kind of handling and maintening the game. Honestly, not much match stayed over 5-7 years with such lack of honesty and non transparency of the localizers, and their approach then (at least in my country) was type of instant-ramen of purchasing permit, utilizing it in few years for fast buck then discarding it. There are a few poblishers/localizers did really excellent job, notably Mihoyo or YoStar, but that is for cellular market and that's sort of afterwards with cheap PSO2 Meseta
greater standard when gamers started caring about such and transparency.
