Has anyone flown the updated 4 class Emirates 777-300ER?

My wife and I will be flying business class EWR to ATH this coming March. According to the current seat map for our flight we will be on the updated 4 class 777-300ER. I have seen pictures where the small business cabin has 3 rows, rows 3-5, where row 5 can be either 1-1 or 1-2-1. Does anyone know which is correct, or are there 2 versions of the updated 4 class 777-300ER? The seat map for our flight shows a 1-2-1 configuration for our flight.
