The Diablo III one is awesome, thanks for sharing that!
Here are some that albeit a little old are still relevant I think (I especially like the “thinking outside the box” of these, which I guess sums up pretty well the whole VFX process)
GDC Vault - Rock Show VFX - The Effects That Bring Brutal Legend to Life - Brütal Legend VFX breakdowns and pipeline
http://www.gdcvault.com/play/1015898/The-Tricks-Up-Our-Sleeves - Uncharted 3 VFX pipeline + some breakdowns
http://www.valvesoftware.com/publications/2011/gdc_2011_grimes_nonstandard_textures.pdf - Using and making non-standard textures in Portal 2
GDC Vault - Low Complexity, High Fidelity - INSIDE Rendering - Rendering of Inside, mostly about graphics programming but some very good VFX breakdowns towards the end
(I think some of you actually made these talks, so congrats and thanks for sharing the knowledge!)
