I did HKG-BKK-HEL a few weeks ago. My understanding from vaious threads in the "other European" forum is that all MD11 aircraft have the new seats and that there are 2 configs. FWIW the aircraft I flew on had the layout you descirbe above. I was in 3C which was fine, but the clear winner on this aircraft is the first row middle section ( I had been offered these seats when I purchased but declined as I'm not a bulkhead fan, however, in retrospect they look fantastic). There is probably 18" extra legroom for these two seats. They use it for the newspaper racks during bording. The clear loser is the second row middle seat as it misaligns and looks to have restricted legroom.

The new seats are alright, a bit too hard for my taste, but I still got about 7 hours sleep. As far as the angled lie flat seats go, I personally find the QF and CX seats more comfy than these. Food was decent, the wine list is fantastic and the service a bit motherly.

HKG and HEL airports are fantastic compared to the dump that is the new BKK
