I'm going to wager we don't see full, final set of proposed changed prior to the actual book. If (for example) the rogue scored well and is "locked" except for some fiddling, we won't get the rogue again. Barring whatever feedback Jeremey and Todd discuss, we won't know if (again, for example) the swashbuckler we saw in packet 6 is going to make it or not. They are going to do that to preserve hype: they don't want to give a "final list" away for free a year before the book is out. They will shroud things in obfuscation to keep some mystery and buzz until preview season 24.
