I'm kind of the odd man out here, since I'm waiting on the cab model, which is coming out after the non-cabs. But for whatever it's worth, I put the deposit down on mine a few days ago and my dealer's district people were telling him to expect the units they had ordered a long time ago around mid April.
My deposit turns one of them into a retail sale which should give it priority. I don't know what effect that will have time wise, but maybe it will at least keep the delivery schedule for mine from slipping past April.
