According to contrailsphotography.com there are only 4 767's left to convert, and then the A330's. All other aircraft are done.
I don't think all the A320s are finished. Their employee website shows 3 A320s due for completion on June 15, June 24 and August 10. Perhaps those are the last of the Airbus narrowbodies.
I doubt A330 conversions will start until after the summer peak. They show the XM
A333 seating configuration as 37J/228Y vs. current 42J/232Y. Seat pitch in Y seems to drop by one inch with the new layout to avoid losing more Y class seats (from 32 and 33 in., varying by row, to 31 and 32 in.)
