Richard Grove has written up a piece on Renderosity and his own blog about his experiences at SIGGRAPH, and what he hopes to do this year.  In it he covers not only what will happen, but how SIGGRAPH wound up in New Orleans after Katrina and some of the new things the ACM has integrated into the conference this year, such as “realtime rendering”:

Other new areas of emphasis at this years conference include Siggraph’s first ever inclusion of “realtime rendering” as a track. This essential means that the games industry is now a full participant at the conference. Will Wright will be giving a keynote address as a games specialist (I guess conceiving and designing SimCity, The Sims and Spore qualifies him). From a machinima perspective, I think it’s going to take some time before there is general acceptance of machinima as a viable artform, especially at Siggraph, which has an academic slant to it already. One of my goals is to be a ambassador for machinima to people I meet at Siggraph. Wish me luck.
