I don’t get the need for Google Podcasts. There is already a section for Podcasts in Google Play Music that I have been using and have subscriptions. Google Podcasts isn’t even smart enough to import my existing subscriptions.
I don’t listen to many podcasts any more now that I don’t spend an hour a day in the car commuting to an office. In fact, most of my recent podcast listening has been using Apple’s Podcast app on an iPad.
