Yes. The main benefits of HDMI 1.3 are audio--it can transport a digital stream for SACD or DVD-A for D/A conversion at the receiver, and it can transmit Dolby Digital Plus, Dolby True HD, and DTS HD for decoding at the receiver as well.
The 1.3 spec also has something about "deep color", which can transmit a bigger palette of colors, but I'm not sure if: 1) any disks have been encoded this way, or 2) a current TV with HDMI 1.3 has the additional color resolution.
