While pretty much everything I'm going to say has already been mentioned, I thought I'd still chime in just so there is another person's opinion. Overall I was very impressed, and it was a great first effort.
Things to be improved
-I do think it is too long, (that goes for any podcast over 30 minutes usually) even though you covered a lot.
- More exclusive info to encourage people to listen. Having ioi or the Source reaveal some exclusive sales info would be great. Or if when somebody has an advanced copy of a game to review, if you could get them on to give a little information about it that would be good too.
-Like previously mentioned, there are parts where the sound quality falters.
-Finally, and I think this will improve as more podcasts are made, would just for the conversations to feel more natural. I think for a podcast to be enjoyable everyone needs to sound energetic/excited without going on too many random tangents (which is why I can't stand the IGN podcasts).
Again, overall I was very impressed and think you did a great job.
