According to Kuo (via 9to5Mac) who bases his analysis mostly on Apple’s online shipping estimates, overall demand is ahead of expectations, and there’s strong demand for the new colors — midnight green for the iPhone 11 Pro/Max, and green as well as purple for the iPhone 11.
I’ve checked Apple’s U.S. website and for the iPhone 11 with 64GB of storage, shipping times are 5-7 days for all colors, except green and purple, which ship in 2-3 weeks.

For the iPhone 11 Pro and the 11 Pro Max, the situation is a bit more complex, with some models shipping on Sept. 20, some in 7-10 days, and some 2-3 weeks, but midnight green does typically ship later than other colors.
According to Kuo, production problems for the midnight green color may be contributing to that model’s lower availability.
