Understand your frustration. I'm not sure what your level of Japanese is, but what I did from the time I joined JPod is download every lesson. Beginner, lower intermediate, the original intermediate series and also upper intermediate.
I'm a lower level intermediate student and still have a few lower intermediate lessons to work through before I get to the old intermediate series, after which there is still the upper intermediate to go which will take me quite a while to get through.
For me, this is a chance to 'catch up'.
As a paid subscriber, I also hope they bring back the higher levels, but having said that, I'm guessing that I have 6 - 12 months work ahead of me before I get through all the older higher level lessons that I haven't studied yet.
