Hold your breath
We already have near 4 others episodes ready (the whole series has already been released in french, so we already have all the timings and such ready).
We plan to release, at least, two episodes per month, maybe more sometimes, it'll depend of the translator (right now, episodes 2-3-4-5 are translated).
During the start of the next month, we'll release our usual monthly batch episodes that we started in September, and in it, there will be "Abel 2 & 3".
About your question about the dvds, yeah, you may find them in Japan in rental stores.
