I unfortunately was not there, but we can vicariously enjoy it via the presentations that are posted on the conference website.
Below is my take on the highlights (in chronological order).
Peter Carl and Brian Peterson
“Constructing Strategic Hedge Fund Portfolios” is wonderful from my perspective. Promoting random portfolios is sure to win my heart. It also discusses portfolio optimization.

“Diversification Reconsidered: Minimum Tail Dependency” takes a different angle on diversification. Portfolio diversity is a subject that has appeared in this blog.
R. Michael Weylandt
“Real-time Portfolio/Market Monitoring with R” tells of the genesis of a package for doing what the title says. Sounds exciting.
