(No, I can't post publicly what the product is, because we aren't letting that news out yet!)
I'm sure there will be snags, but I'm pretty confident that the bird will fly. Not for long, perhaps, but enough to prove the point. I'm rather looking forward to sending the e-mail to everyone in the company announcing the good news: we're pregnant! In xx months, we're going to have another product!
And so to sleep... next update will probably be Wednesday, after the main event. (This, by the way, is also why I haven't been posting much lately. Product management coming up to milestones like this is hectic!)
