Today's the public showcase of MH's A330 refitted with new J and a few Economy + seats.
Pictures from malaysianwings.com forum:

Showing the staggered J seats with shoulder/chest belt buckle visible below the headrest. 1-2-1 and 1-2-2 config.

Reclines fully flat now.

Some info.

Seating layout, less 1 row compared to current offerings.

Economy Plus section that's directly behind Business Class. Only 2 rows, same 2-4-2 configuration.

Economy Plus extra reclining. Missing one window on the 2nd row.
Looks like Row 7 of the old Business Class was removed and replaced with 2 rows of Economy Plus.
