Not sure if this is new or useful info but talking with my geeky anime friends I got this bit of news.

CLAMP is having a super special promo right now because this year marks their 15th aniversary making manga/anime. Because of this, Tsubasa Chronicles and xxxholic, their two current projects, is showcasing all the work they have done for the past 15 years (use of the old character modals) as well as just being a huge undertaking themselves with overlapping plot and such. It's a huge deal and is being accompanied by a special collector's chess set you can buy where they ship you like 1 or 2 pieces a month with all the clamp characters as the chess pieces. I'll make another post with a link to the chest set but for now I should probably be sleeping.

Just some info for those wondering why CLAMP was using old character modals.
