About the only hints you can take from it is in the Warp statement about what they lost
Forthcoming albums - CANT's 'Dreams Come True' (Sep 12th), Plaid's 'Scintilli' (Sept 26th) and Rustie's 'Glass Swords' (Oct 10th) - are currently being manufactured. We know PIAS are working hard to get alternative distribution in place and we are hopeful that the release dates of these albums will not be affected. Most UK copies of Battles' new single 'My Machines' have been destroyed, although the single will still be released digitally on Monday - with some limited 12inch stock available at Bleep
So, stuff in that warehouse was stuff that was either back catalog or stuff that was due for imminent release (Battles). Makes sense: it's a distributor. The Plaid, CANT and Rustie releases are in manufacturing and if they had done a drop to the warehouse they have enough time to go out unaffected through a different channel.
No mention of BoC in that list. Unless they had pressed a bunch of BoC stuff to do a secret, sudden release in the next couple of weeks (highly f unlikely) it wouldn't have been in the fire. So it's either in pressing at the moment (and they've just not mentioned it, because it's not been announced), or is scheduled for some point after the Plaid release, because the Plaid album, in Warp terms, is pretty huge so you can guess they want to get a good chunk of it out of the way before they move onto anything else. My guess is firmly on the latter, just on balance of probability.
Upshot: any new BoC was very likely not imminent for release, is most probably coming some time no earlier than the beginning of October AT LEAST, cos of everything else they have to get out the way first. Also, whatever the planned release date is, it most probably won't be delayed by the fire as they can sort out alternative distribution in the mean time.
