That link says it will be direct injected.

All the other information I have seen was pretty specific that it will be port injected.

EDIT: This must have been a typo on their part. In the engine cutaways you can clearly see it is port injected, and there is no where in the head casting they show for a second set of direct injectors.

I'll be honest, I am not in the market for a brand new truck. They are all out of my price range! But I have been checking every other day to see if ford has release the power numbers on the new 7.3 Gas.

So for a neophyte, what is the difference between direct injected and port injected and why does it matter?

Direct injection is directly into the combustion chamber(like diesel engines). Port the fuel is upstream and mixes with air through the intake valve. Theoretically direct injection can be cleaner with gains in mpg and power.
