Bandai Visual USA President Tatsunori Konno has updated his blog after his company announced the delay of Shigofumi: Letters from the Departed, true tears, and sola. He notes that the move is part of a larger strategic shift that affects Bandai Visual in both Japan and the United States. Both regional arms of Bandai Visual "are now rushing to reschedule all future releases, focusing on Blu-ray" for both new and old titles. Konno emphasizes, "It does not mean we will not release any standard DVDs at all, but we will concentrate on expanding our Blu-ray catalog." The company plans to reschedule the three delayed titles, but not before summer.

I was afraid they'd bump off the sane part of the family, Bandai Entertainment, but apparently it worked out differently, which is a relief. Too bad for delayed release though. They may still hope to strangle the sane Bandai subsidiary gradually as BD takes over the DVD...

UPDATE: Astro observes:

They’re an awfully young company to be re-inventing themselves.

Ouch. But it's understanable:

Now I’m sitting on three different pre-orders (5cm, NHK, and Shigofumi) with no expected date in sight. Sheesh. I’m never going to order an in-progress series again.

You said it, brother. I saw Gurren-Lagann DVD v.1 on Amazon today, and very nearly bought it. But then I thought: "let's wait, see how it goes..."
