Yes. But to say it is still "up in the air" (idiom). Some Angelenos (citizens of Los Angeles, California) say, "two thousand ten", some say, "two thousand and ten". I have been saying, "twenty-ten" and now more and more people here are saying "twenty" instead of "two thousand". Why? We are too lazy to say "thousand". How to pronounce 2000's? As lazy as I am I would pronounce it: "twenty-ought" plus a single digit number. "Twenty-ought one", for example. But I'm an old cowboy from Colorado.
