Surprise! Double Fine's lovely turn-based RPG Costume Quest just popped up on the iTunes store. Between this and The Cave last week, could Psychonauts iOS be on the horizon? Here's hoping they can get the rights to Day of the Tentacle, too.

Ron Gilbert's The Cave will be released on January 22nd for PSN & Wii U, and January 23rd for XBLA & Steam. Only a week!
