Ok, so I have actually seen the videos (the torrents are out there, if you're not new to JAV and know where to look it shouldn't be that hard).
There are clips (between 30' to an hour) for Yuma Asami, Hana Haruna, Mika Kayama, Julia and Rina Rukawa.
My impressions:
1) Yuma Asami and Hana Haruna are as pretty down there as they're everywhere else. Nice shaped, tight lips and cleanly shaven. Delicious.
2) Julia on the other hand is not as hot. Somewhat soggy lips and a sloppy shave on the down half.
3) As most already knew, the use of condoms during penetration is obvious, but the cumshots are condomless (many people accused S1 for years of using condoms for blowjobs and cumshots).
4) The semen is real (at least for the facials displayed in these scenes, you don't need to be a genious to notice that half the creampies in the business are fake), and so is the squirting of the actresses.
5) While nice to see, it's kinda messed up that somebody (probably a Hokuto Corp. employee) leaked the videos. The actresses' contracts most likely protect the "privacy" granted by the pixelated mosaic. Somebody is going to be on the job market by the time this is over.
EDIT: They are actually charging poeple for these already! The scumbag levels are off the charts.
