MVM have confirmed yesterday that their planned release for Mayo Chiki! has been delayed until next year.
The reason for the delay is that it has been revealed that there is no english language dub planned for the series. One can only presume that is there is still no dub planned for next year then it might not be too surprising to see it disappear off the radar all together but we will have to wait and see what happens.
MVM have decided to move their release of Rozen Maiden: Ouverture forward to November to fill in the void in their release schedule.
