From what I know, the DVD963SA is the new unit. JandR is taking pre-orders on this new machine and it is selling for about $385.00. Check at Phillips site for more information on both units. The 963 is available in Europe but it is going to be available in the States at about mid-March.
I'm also looking at it as a good cheap alternative to join the SACD wagon. Although the tittles available are limited(based on my taste), it provides terrific video performance, is compatible with anything less DVD-A, I heard saying it upsamples regular red book cd's and it is a good SACD player. It also has coax out for DAC connections (if neccesary).
Hope this help and, please, verify it.
Regards,
Jose.
