No one knows what this Smaug will look like in real bronze.
This is me partly guessing, but one reason for not doing a pre-cast discount would be because your not taking a risk. I would be massively surprised if John and Richard, etc wouldn't be anything other then satisfied with a Smaug that didn't turn out great.
As such, there may well be some "AP's" if the first couple of goes don't produce a statue that they are happy with. After that, you will then get the #1 and the others will likely never see the light of day. Then again, I get a feeling that Weta do have some experience with real bronze work, so unless something really goes wrong, they fully expect to capture the detail of the original sculpt.
As for Howe Smaug vs soem future Hobbit Smaug, assuming that licensing, etc all work out, I do half expect the 'Daddy Rog' Hobbit Smaug. Having said that, I still doubt it would look all that much different, still going to be a dragon. Now you don't get much more iconic then Smaug on his gold, so if the Hobbit one is much the same, then just like the Baby Rog had no impact on Daddy Rog value, I doubt any future Smaug will impact the FB Smaug, just like the FB Smaug won't impact the real bronze one.
On the subject of using the same wood base and making book, I can understand any bronze owner liking those to be unique, but isn't the ral bronze enough
Besides, its really nice for us FB owners and its because of us that the bronze ES is now 1/3rd smaller and costs $1.5K less, so gives us a break
