I'd take EB_dood's claim with a large, mountain-sized grain of salt, but it does seem to hold a little water. I've searched stores here and where I was at Christmas (gf's parents, 6 hours away) and have only seen two component cables in the wild, which included Mad Katz branded at a GS, and a lone pair of Psyclone's $60 at a Best Buy.
Meanwhile, none here locally between two GSes and Best Buy. Which does bug me - I've heard the React cables from Best Buy are pretty good for $25, and I've got some credit there, so I could snag them cheap until I get Nintendo's.
But this is pretty stupid. I have no clue where they are and they SHOULD be out by now. If this hasn't sent a message to Nintendo, I don't know what will.
