Bolt pattern for 2005?

Pointless, like the TBird going to 5 on 4 1/4"? Or the 97 pickup going to a weird metric 5 stud pattern, and SEVEN lug on the F250, and a different 8 lug on F350's... just so no older wheels interchange... i wouldn't put it past them.
 
i can understand the offset but why would they change the pattern if the bullet wheels will be offered on the base model. I am sure they have overstock and its more cost effective not to have to retool the machines that make wheels.
