Yes, that's very true! Making this book without being able to make it complete, yet, is just a pity.
They already annouced they would do a second edition to add to it once the Vintage Collection is done (which it won't be for another 5 years I hope!).
Well, if you change your mind I ordered a second book just before checkout. It's the basic version for $60, but I didn't want to spend $150 on it just for the bonus features...
If you want to have mine, you can have it! I'm afraid prices on ebay will explode for this...
