Yup, the game will be made entirely open source, with CC licensed art and music included. Some of the backend is currently under NDA, so we cannot make the source code public yet, but it's already on Github. We're currently thinking this will happen some time in November.
so is that possible to "open" the game (cos right now those pokemon only available in london and SF) so everyone can play that everywhere? (i plan to let attendees to play this game at future gdg events)
