Will Fancy pant World 3 ever come out on PC or just for online play?
[MOD EDIT] If you found this thread while searching for information, let's clear things up a little.
No, there are no plans to port Fancy Pants Adventures on the Playstation 3 and XBOX 360 to the PC. Mainly because Fancy Pants Adventures for console focused on multiplayer, while the FPA Worlds for PC (browser) is a flash game focused on the experience.
World 3, which is the main world for FPA for console actually comes from World 3 for browser. It's just that World 3 for browser ain't done yet.
