I will probably get a PS3 eventually, especially after 1080p is more affordable.
It seems to me that the PS3 was just released too soon, since it has limited availability, limited games, limited display availability (limited 1080p base due to expense and variety of models), and a few very frustrating bugs. The pressure to release gaming hardware is becoming as great as the pressure to release software.
On paper, the PS3 is a must-have for Home Theaters. Gaming, BlueRay player, movie downloads, and now you add SACD, all at the highest resolution available. The XBox 360 seems to better fill the niche for the current state of Home Theaters.
But I digress...what is the output for SACD? I would assume it is digital optical.
