I tweeted Nick Kokonas back in early July about the other cookbooks and he said that they were "nearly done...just need to encode and go". Anybody with a connection know anything more? I loved cooking from the Paris book and am dying for more.
I was beginning to think that they had abandoned the eBook idea, but now there's a glimmer of hope again. From a piece in Chicagoist about Christian Seel, the guy who does their promo films, and who compiled the original Paris eBook:
Chicagoist: You mentioned the electronic cookbooks earlier; do you think they will be released?
CS: They have been talking about a couple different things that I can’t really share at this time, but yes, I am still photographing and we are still producing content. When and how they are released publicly, I don’t honestly know.
