Icom IC-7610 shipping date pushed from DX Engineering

The shipping date for the new Icom IC-7610 has been pushed back to 12/19 now. Not sure it will arrive for xmas. It makes one wonder how they can't know the exact shipping dates, and secondly if date is going to be missed why not just say so instead of at the last minute posting a new date.
