I could be wrong, and if so please correct me, but they have pages now up on infinity.disney.com for Ronan, the Green Goblin and Loki. I don't remember seeing them when I visited a few days ago. Links provided below straight to their respective pages.
RonanGreen GoblinLokiEdit: As of now (9/6/14 2pm), I think they need to fix Ronan's page... The banner at the top shows the Loki banner image instead of Ronan's banner image.
Edit 2: Ronan page/banner fixed
Edit 3: Last edit. This is just weird. When viewed on Safari the Ronan page loads properly, but when loaded from Chrome, the Ronan page displays a Loki banner. No big deal, nevermind I mentioned it now...
