The 6.2 would definately be the engine cut from the lineup. The Ecoboost and 5.0l make up the overwhelming majority of sales. Not to mention the 6.2l is terrible for Ford's CAFE rating.

Dropping the 6.2l from the F150 has seen passing references from Ford execs quite a few times in the past. Not that long ago Ford wanted imput from consumers on whether they would consider buying an Ecoboost Raptor over the 6.2l.
