The 4 and 7 has been an ongoing debate among marketing academics, it seems. I recall the "right" answer alternating course by course through school, pending the professors interest.

If I recall, the 4 P's are the standard marketing mix, with the 7 P's being called the extended marketing mix. FWIW, the 4 was definitely more central at my school.
