Check out The Minority Report; you might like it!
The guys over at Gamer 2.0 have created The Minority Report, a 30-minute (or so) podcast that will air weekly.
Whilst not specifically PS3-related, the guys have some good insight into topics such as the EA bid for Take Two, whether the PS3 will take over from the Xbox 360 and a segment called 'buy or sell' where they throw out a situation and then decide if they 'buy' the scenario or 'sell' it (like it or throw it out).
Keep it up guys - we'll be listening. Should PS3 Attitude start a podcast? Put your thoughts in the comments section...
