I agree with pretty much everything said above.
Colt has stated they are going to make as many copies of their basic anniversary model, the O1911ANVIII, as people will order from 11/10 to 11/11. You want one, they will make it. The cased/engraved ANVI and ANVII models are a different beast, are going to cost quite a bit, and at some distant point in the future the ANVII model might be worth a little bit more. But almost certainly less than if you take it's 2011 purchase price and put that amount of cash in a good stock mutual fund instead.
So eventually, it's going to be like the Harley 2003 anniversary models. There will be so many more of them out in the marketplace that they will actually end up being worth LESS than the standard production model from the prior or later year. Also, the roll marks on them are distinctly un-attractive, and the finish entirely wrong for a 1911-period gun. The smarter folks I know are putting away an ANIB O1911 or O1918 WWI repro as the definitive period-correct colt reproduction.
If Colt would have made it detail-correct to the 1911 style commercial guns, put on a correct finish and then limited it to say 5,000 or 8,000 guns, they would have had a winner. I would expect in the year to two after the anniversary models end, you should be able to get them in the secondary market at about a 20% discount to their dealer price. I'll probably pick one up then. If it's ANIB, I'll leave it as such, or if it's got a little wear on it I'll make it a shooter. But I won't be paying dealer cost for one as a collectible, that's for sure.
