Kaz told me an interesting bit about the OVA:
--
Oh yes, talking about seiyu, there was some report on the TFC about the 
recording of the 3rd OVA. All the staffs of the previous series joined 
this recording and it seems that they enjoyed being together again. They 
say that in the 3rd OVA, there are some recollection scenes of the 
previous videos. For those scenes they didn't use the old recordings but 
they actually re-recorded again this time. So there should be a slight 
difference in the voices. After all, there are several years blank since 
the last OVA was recorded, you know. I wonder if I can recognize the 
difference!

Should be interesting to hear!
