I couldn't really watch it, unfortunately, but the general feeling I saw on Twitter was that this was a vast improvement from last year's WWDC.
Gizomodo has a nice round up of the features announced. HomeKit sounds VERY interesting... it'll be fun to watch vendors try/not try to take advantage of that. And integrating Shazaam directly into Siri is pretty cool - but are people really hearing music that they don't recognize when they are out?
This is nothing too knew. They have been talking about Bluray for quite some time. They claim 2010 is when it will appear. I say 2030 before it becomes standard. With all this new technology comes all this upgrading and upgrading.
