Don't cancle your orders. Yes, it has been a long wait but I bought from Rocky Nook to support the community here. A few more weeks won't make or break my heart and I'm sure it won't prevent anyone from taking the perfect picture. You shouldn't be out any money yet.
I bought the D7000 in Oct 2010. It was my very first DSLR and my very first Nikon. I've read the manual more times than I can count and I think I'm taking ok pics with it.
