I believe the SF show was already organized in advance of the NY one - it was advertized on the site before the NY show had started. It's a bit close to CES2005 so it's likely several manufacturers will skip HE2003 SF and just do CES. At least that's what Bobby from Merlin told me...;-(
Home Entertainment Show in SF in November 2004
Looks like the success of the NY show in May 2004 may be the reason for its return to SF sooner than expected. I just found out by surfing on the HE Show website. See you there!
