Riot has a site where you can view the PROJECT: series as it updates, it already has Yasuo out, and it has hints to the other five skins. PROJECT: X

There are also "traces" which contain small teasers to each champion.

"Dark sight..." is obviously the Zed teaster.

"Weaves, unweaves..." is probably Irelia, flowing through the battle field with "dancing blades"

"Piercing flame..." is in my opinion Varus, though I may be wrong about that, I don't have that many other ideas.

"Brilliance in pieces..." is I think Kalista, and is the only female champion hinted at thus far.

The final trace has no teaser as of now, merely "Trace lost" as soon as it is clicked upon. This may be for a champion who has no memory of their past, or it may just not be ready yet.
