I have had hands on experience with virtually every wireless HDMI solution being proposed. First for the UWB solutions 30' (10M) MAX and worse in many environments. Second, they all truncate content somehow- either recompressing or artfully dumping some image component not deemed necessary. Third and most important they will be between $450 and $800 retail. You may as well buy another MD.
SDI won't make it to the consumer market- its not considered secure. However Displayport will muck things up a lot (as will USB video). The CE industry is possibly the most self destructive industry there is. Instead of learning from the VHS Betamax mess they have chosen to repeat it endlessly. DVDA/SACD HDDVD/BluRay HDMI/Displayport/ etc. Marx said, "History repeats itself, first as tragedy, second as farce."
