A couple of thoughts, if I might?
First, as an old-school modeller, I'm definitely in. The biggest commitment here is nothing more than time. Financially, it's a no-brainer. Making sure I have enough on a credit card is nothing more than sacrificing a burrito combo a week. Additionally, that two-year window gives me all the time in the world to decide on if and how much I'd like to 'accurize' it with some Shapeways parts.
This is like a 'grail' opportunity to me. (And I'm not worried about sudden cancellation. DeAgo has a loooong history for this type of thing and this is easily the most 'pop culture' item they've ever offered.)
AND I'd still be in even if I had an MR Falcon, too. Between the bajillion customization options and the wall mount, I've already got a ton of potential display options going through my head.
I also don't expect the MR to depreciate in value in any way on the secondary market because of this. The MR is what it is and it's a case of apples and oranges to me. If Porsche suddenly started manufacturing trucks that looked exactly like a Ford F-150, I wouldn't expect Ford to drop the prices on theirs.
