Hi, I emailed them earlier in the month then forgot to post..The publisher said there was a problem with distributing the English version, but they hope this to be solved next month or by Christmas. Their reply, edited for clarity:
... Our publisher had some problems with
international distribution and is changing something...Our publisher is sure that the situation is going to be clear and the
second episode will be released before christmas. We hope in november...
