They wouldn't neccesarily need to delay thier own goods. If manga were to do a deal whereby they shared the raw discs, and Manga paid for the additional costs themselves as part of the license agreement, surely that'd get round the issue.
As long as a copy was supplied to the BBFC early enough, I can't see it delaying the release over here by that much, and surely far less than the current year or so which is common, and manga could distribute the costs amongst there stock.
Providing the cost isn't TOO excessive, we'd then get the media only a short while after the states, and slightly more expensive than the states, more or less annulling the import needs, where we have to pay more expensive international shipping and risk import charges.
Now I don't know that much about BBFC costs so I could be wrong, but if doing it this way meant it only cost on average £3/5 more than a US buy, without the extra shipping costs or import risk, and with material arriving quicker and with greater availability (because lets be fair it sounds like Funi tends to grab UK rights anyway), wouldn't we be willing to pay a little extra? (I'm not talking like £10-15 extra).
Potentially not having to do thier own masters etc with Madman etc in OZ could potentially reduce some of the costs anyway, helping these additional manga costs to even out.
From my point of view; it'd be quite interesting to see a breakdown of the various costs; and see realistically; how much more expensive it WOULD be to do things this way for BD releases. (As lets be fair BD releases here and in the states will be 24/23.976 anyway due to the BD standards, which don't actually include 30FPS except as interlace IIRC)
