Update:
I listened to part no. 4, Counting and it was quite funny, beginner's stuff though - as Heather told me already.

The situation is that the guy (what's his name by the way?) does the introducing and explaining in english, the japanese girl (and what's her name?) does the japanese part and both together they do the repetitions. So you get at the same time a native speaker's japanese and the learner's japanese with an accent which is probably quite encouraging when you are a beginner yourself. At the end of the counting podcast the guy promises to add soon stuff for more advanced users. So we should keep an ear on it;)

Thanks to Heather, I heard from this Podcast (Audio and Video). I'll try it out and if it's good, I certainly will talk about it here.
