Well, at least quite a few of them are available. This is the annual meeting that just concluded in early June in Montreal.
If you go through the listing on the left side of the page, any of the presentations that are in BLUE have a powerpoint presentation connected. Save the ppt to your computer and then view it normally.
again, I wish we had access to the entire presentation and not just the slides, but there is still lots of meaty content here.
