YGE Shop has just posted an announcement to its site for the Solar Concert DVD saying that the release will be postponed to February 8 from its original date of January 26.
Updates in red after the cut.
Reason given is that the manufacturer is unable to meet its shipping deadline due to the upcoming Lunar New Year holidays. This will likely affect
both the Japan and Korea versions, but this is still subject to confirmation. (As of the time of this posting, YesAsia and AmazonJP have not yet changed the release dates on their site. DVD Heaven has already updated the date on their site.)
Update 1: YesAsia has also changed the date on the release of the Korean version. The shipping date of the Japan version has not yet been changed on either YesAsia or AmazonJP.
Update 2 : Good news for those who ordered the Japan version. Looks like it will be shipped on time after all. Only the release date of the Korean version has been moved.
We will update this post once more information becomes available.
