Gary,
I wondered the same thing a while back when I bought my 10-20 via Amazon and called Sigma. They told me it did not matter the warranty was 4yrs. It is their standard warranty for the USA non-gray market EX series of lenses. The non-EX lenses are only 1-yr.
But that was a year ago and if anyone is buying from Amazon directly (remember just because it is sold through Amazon of the item says "order fulfilled by Amazon" does not mean you are buying from Amazon).
I think is out be a safe bet that the EX lenses purchased from Amazon are indeed not considered gray market and thus have the USA 4-year EX warranty.
