Yes they do come with HID's. But i've heard some rare cases where Honda switched HID's back to regular halogens on some cars to save the environment. If you got halogens instead of HID's i'd go back to the dealer and yell and scream and demand that they replace the halogens back to the intended stock HID's. Go do it. We're behind ya all the way.
If your dealer tells you otherwise come back and post here. We'll boycott Honda/Acura if they refuse to give you HID's.
