Apple has removed Podcasts in it's music App in the latest developer build of iOS 6 leading many to speculate that they are gearing up to real ease a dedicated Podcast App, much like they did for iTunes U.

All Thing D has weighed in:

"People familiar with Apple’s plans tell me that when its new iOS 6 software becomes widely available this fall, podcasts will have their own app, where users will be able to discover, download and play them on mobile devices. Users who access iTunes via laptop and desktop machines will still find them in that version of iTunes, though."
