it true that the upcoming ones are project ashe and project katarina? cause on "surrender at20" there are pictures of your store with project kat and project ashe t shirts but then removed. (not sure if t-shirts)
I can tell you from the decisions RIot makes with their champions, Tryn or Draven will be part of it.
As of now it looks like Ashe and Katarina will have Project Skins.
Riot probably won't answer until the skins will be out on the PBE (Which will be the answer itself), for reasons such as that any unreleased/in-development content might bump into issues before release, so Riot wouldn't want to create expectations for players and then have them disappointed because something didn't work out.
If 
have a project skin i'll definitely buy it even tho the skin is ugly. Ashe is the best!
