The DRM scheme will likely stay the same and the peanut formatting is dead simple to decode, it's essentially a very basic HTML-type markup language.
My understanding is that B&N (and Sony) will be transitioning all their books for sale to ePub format, so hopefully we can re-download all our purchases in the new format. It seems silly to duplicate titles in their system, rather than overwrite the old versions entirely.
I would agree, they have years of customers and no reason to cut them off. I suspect they will not kill this format. There is minimal overhead to keeping it and with the new deal with adobe to manage the licensing they won't have any support from that part of the format so that really minimizes any overhead. They only need to keep copies of the books so that people can redownload them.
