The wait may be slightly longer than people anticipate. Since HDMI 1.3 can transmit the new HD audio codecs natively, manufacturers won't miss the opportunity to incorporate new format decoder chips into upcoming receivers and pre-pros.

Are those chips ready and shipping? I know they are for players (with some limited functionality) but I don't know if chip makers have them ready for receivers and pre-pros.

If I were a manufacturer, I wouldn't just graft HDMI 1.3 capability onto my current models. I'd definitely wait for format decoding chips for DD+, DTS-HD, Dolby TrueHD, etc. No sense implementing only part of the 1.3 spec. So this may take longer than people expect.
