The Mega will continue in the HD pickups through 09 and be cancelled in the light duty for 09. You will see the new Crewcab probably by spring time 08 at auto shows and such. I am 90% sure the new Crew will be similar size seating space as the Mega, but missing the storage area behind the seat(Toyota like). This will allow for a more manageable sized truck to cruise around town(shortbox), and make the longbox model a more realistic length as well. From the sounds of it, this new truck is sweet!
