Ok, I have typed this out twice already both times this blackberry bit me with its damn microkeyboard and erased everything.
I just thought the rumor was funny. The F150 diesel is still in the same place it was last month, on hold indefinitely. There are F150's running around with diesels, some aren't 4.4L's. They aren't 6.7's either. The future of the light diesel depends largely on how the future emission and fuel economy regs pan out. Hopefully that will be more clear by the end of the year.
There is a new slightly more fuel efficient gas motor coming for 2011 for those who can't wait for more MPG's out of their truck.
