HDMI 1.3 won't be showing up in receivers for a while yet. Transcoding to HDMI from analog formats requires conversions that aren't simple. Who knows when and who will be willing to undertake them at what price? In the meantime, the analog equivalent of the new DD and DTS formats through the tried and true 5.1 channels sounds awfully good. I, for one, wouldn't sacrifice the opportunity to hear them just because HDMI 1.3 weren't available yet. But I imagine that lots of other people might.
