@Mother-Vain Well the game is set 1000 years in the future. One thing to note is that IDOLA takes place in the far future of PSO2's timeline where ARKS has disbanded. NGS may be taking place after ARKS has disbanded, hence why you don't see any ARKS logo on the new outfits, so this may be more of a story thing with the new outfits. Also, a new outfit really gives it that new feeling. Plus, the colors on the four characters seem to match quite a bit now, where as before they were very distinct.
The main thing to note is the line,
Naturally, ALL character creation info from PSO2 (including items linked to emotes and other previously registered data) will be compatible with PSO2: NGS!
What exactly does other previous registered data means is the big question. Because things like base wear and inner wear are character creation info that is registered to a character/account. They even emphasized the "ALL." It would be strange to not have some of the outerwear that went with the base and inner wears wouldn't it? So right there there is a huge implication, while at the same time, leaving it vague enough for skepticism (which honestly does annoy me, I prefer blunt answers on situations like this). I am honestly of the feeling that outfits will transfer as well; while I can't say for sure due to the vagueness of the language. I do believe that fashion is a big enough part of this game and the profit margin of the game, that Sega wouldn't want to risk it.
The porting of Ash's default outfit also begs some questions. Like sure it is only one outfit, but still, it can mean something.
Part of this does depend on how long this has been in development.
Also, I checked the Japanese site and one of the links on it is actually to submit an application for a job at Sega. Like it is not a hidden away link, but rather visible one.
Plus, the game literally just came out this year in NA. I doubt they would want people in NA seriously hold back on their cosmetic purchases.
On a different note, I still can't get over Ash's new face. Sue and Rupica looks really nice, but Ash... I feel like something went wrong somewhere.
