Top 5 things I would like to see at SIGGRAPH based on what I know so far

I'm not one of the lucky ones going to SIGGRAPH this year, but I've heard about a few things already that have drawn my attention! Aside from the talks on real-time rendering and shaders, there are a number of hot topics, demos and products that have been announced - here are my top 5 based on what I have read.

• Stereoscopic 3D
  There will be autostereoscopic displays (i.e. no glasses required), talks dedicated to stereoscopic 3D, screenings of 3D shorts, etc. 3D stereo imaging is finally going mainstream.
• HP EliteBook Mobile Workstation
  Kind of ugly, but featuring FireGL V5725 or Quadro FX 3700M graphics with an Intel Core 2 Quadcore Extreme with 8GB of RAM. Also interesting and certainly sleeker, but doubt they are showing at SIGGRAPH, are the new line of Dell Precision mobile workstations.
• HP DreamColor Display
  30-bit color LED backlit widescreen driven by FireGL or FirePros with Display Port - can you really tell the difference with 1 billion colors?
• Radeon 4870 X2
  Yeah, it's a gaming card, but it is the first dual-GPU card that scales up or down, and while not certified for CAD, will do well in less rigorous markets
• OpenGL BOF with a discussion of OpenCL
  Lots of controversy from game developers about OpenGL 3, although it appears to me to be a sound evolutionary step for the professional markets. The clamor at the BOF will be interesting. Of more interest to me though will be any news about the OpenCL working group - the new platform-neutral standard for GPGPU computing (presumably subsuming Nvidia CUDA and AMD Stream)
