I have yet to hear SACD, but I do have DVD-A and I have to say I am very impressed with the formats ability to bring music closer to its analog cousin - the LP. That said, I think the market for SACD and DVD-A will remain since there is a sub-culture that is already aware of their sonic capabilities and will more likely be sold in specialty shops only - that is if MP3 music takes over.

In my opinion, it was the consumers hearing a difference between CD's and LP's (on standard consumer gear) that allowed CD to become so succesful. The same should be true with DVD-A and SACD but everyone seems to be focused on MP3. To be honest, there is very little sonic difference between CD and MP3 (that point can be argued for sure), but the hope is more affordable "universal" DVD players will be released to allow the consumer to finally experience the sonic quality of SACD and/or DVD-A.
