I suppose one should automatically assume all their release dates will be off by at least half a month, if we're even that lucky.
I've had to delay some of my own purchases lately, which means this is something I could personally tolerate, but the picture still looks rather ugly, when corabined with all their past quality problems and the general decline in the extra contents of recent Bandai releases.
I'm just speculating, but I imagine that they might have made more money from, for example, their initial Code Geass release if they had abandoned singles entirely instead of trying to go through some weird transitional phase. It's been said before that they shouldn't have tried to make so many different editions for the same release, but I think their mistake there was trying to sell singles and collections at the same time. It would seem that the title did in fact sell, which is good...but perhaps not enough to cover their production costs?
They've had similar, if not even worse, problems with other releases before, but that's the one I'm most familiar with.
Not to mention there's the issue of misleading solicitations. Nobody actually thought there would be a Part 4 for Code Geass R2 until the orders for Part 1 started to arrive and as a result it wouldn't be surprising to see something similar happen again. Unfortunately.
