And I acknowledge that it is an assumption, hence the "likely". However, I cannot find any other product that uses the BV-5JW. The other high-end non-replaceable-battery Nokias, the N8 and the E7 use the BL-4D, which is a standard one, and is documented at nokia.com. Glancing through the models, I also saw that no other battery had a "BV" designation. It was mostly BLs and some BPs. Finally, on the repair manual the battery was completely unmarked, without the Nokia iridescent seal that "normal" models have, although this could just as well be because the dissected N9 was a prototype.

I don't know, I have a strong impression (that I cannot concretely prove) that this will be an item that is supposed to be only in the hands of Nokia tech and service guys, not consumers. Maybe this could also be used in a WP7 model if it has a unibody structure, who knows. I don't think, though, that we will be able to buy this one.
