I believe, based on my conversations with Chas and the rest of the team, that if printers proof came back looking like crap; we'd delay until they were right. When it comes to scenarios, articles, counters,and boards, we either all agree or it goes back to the table until we do. We've all experienced the challenges and issues that products rushed out the door cause, so we want to eliminate in advance anything that might result in questions or errata.
Now keep in mind, we're not perfect, but our goal is to be 100% errata free. Product that you will truly enjoying playing, not just owning. We believe we can and will get there and that very soon we will be "proofing the pudding" if you will.
