When they say project skins realesed during patch 6.15

It will come this Thursday if we go by when the dark star skins came out (6/16) to when the update was (6/14) as well as the pool party (7/14 update was 7/12)

well obviously later because the patch has been released and the skins are not out yet

Usually later.

No its kinda here. Look at this post: http://boards.na.leagueoflegends.com/en/c/miscellaneous/hAn0sXAY-does-this-loading-screen-picture-look-great-project-yas

So sorry for being impatient but will it be like a day or so or just later today
