im just happy we finally have a well-accepted, universal, single cable solution for hooking up everything basically. and some day, wireless-hdmi will be king. no more worrying about what connections a tv has before you buy it, no more worrying if it supports 1080i or p or 720 over 480, its all getting much more simple.
Don't forget about display port--it stands to throw a wrench in things. What I hate about HDMI is it's lack of settling on a standard yet. PCI and PCIe are much better at making standards that don't get tweaked every 3 months.
