I seem to recall that wwdc videos were a for pay feature in previous years (I was at wwdc 07, 09). But what's interesting about this is that this year I went to google I/o which is in it's 3rd year, had 5k+ attendees and it goes without saying that google would release all the videos for free.
Apple would do well to drop the $99/year dev tax as well (I'd consider paying to be in their market, but paying to just developer for my own hardware seems off).
Apple is feeling the pressure of competition.
