SCPH-1000 also has an S-Video connector and is quite hard to find so I don't know, non-Japanese 100x units are the same as SCPH-3000. I don't see changes anytime soon but audiophiles may push up the price of SCPH-(1,3)00x units.
Edit: The switch was around 2004 as My sister and I got GameCubes for Christmas, the Jet Blacks were DOL-001 and the Platinums were 101 so there may be a bit of a premium on the Platinum.
