This apparently does not affect Bandai Japan and is only for the Bandai Asia releases.
Singapore’s Fujiya Character & Hobby Shop is reporting that they have received a cancellation notice for the SH Figuarts Iron Man and War Machine that were coming from Bandai Asia.
Again, this only appears to affect non-Japanese releases as site sponsor HobbyLink Japan has not changed their pre-order status on these items and they still list a May release.
Here’s the full note from Fujiya Character & Hobby Shop:
NOTICE OF CANCELLATION
This morning we just received an email from supplier stating that both S.H.Figuarts Iron Man Mark 6 & S.H.Figuarts Warmachine have been cancelled by Bandai due to licensing issue.
No further detail was given, but it seems like the issue only affect distribution under Bandai Asia.
We will check with the Japan side whether it is possible to secure some stocks. But at this point, we cannot promise anything.
Apology for any inconvenience caused.
