I'm absolutely staggered how slowly manufacturers are adopting HDMI 1.3.  People can remonstrate all they like about how incremental many of the improvements are but I think they miss the point... I'm going to be spending the better part of three grand (possibly more) replacing my system - there is no way I am spending any of that money twice to upgrade something where I jumped too soon or end up feeling hard done by... that's why I have steadfastly held out for 1080p/24 TVs and HDMI 1.3 end-to-end... if it's taking this long to get HDMI sources how long will we be waiting for a decent selection of AV Amps with it in? 

To counter my own argument a little this BD Profile 1.1 thing makes me wonder if the flood of new features will ever slow down long enough for me to commit - my rule of thumb is going to be, if it affects ultimate picture or sound quality - wait; otherwise forget it... they'll probably provide asoftware patch anyway... 

Also I'm very interested in this 72Hz thing - very clever.  It's things like this which mean I'm leaning towards buying everything from one manufacturer because of this kind of integrated thnking (though I doubt it's patentable so I guess everyone else will try to jump on this bandwagon).
