I just had a chance to fly on one of these 319's. It was OK-PET, serving PRG-AUH on Nov. 20, 2011.
I was very surprised when I got onboard. I am used to the standard 319's, like the one that took me to PRG from TLV that very same morning.
This one was nothing like it - at least not up front.
There were 3 rows of business on the A(B)C side and 4 rows on the D(E)F side. The pitch was excellent - especially in row 2 AC - there was no way you could reach the bulkhead, even when fully stretched.
The seats were manually controlled and far from full recline, but were a significant improvement over the glorified coach seats turned to business class seat product that I'm used to.
Apparently, there are 4 planes with this kind of business class cabin.
I hope to get these planes lots more in the future (very unlikely, since my usual route is TLV-PRG)
