Well, they should start getting some more in next week, and what's the alternative? Nobody else has them either... To be honest, I'm a little peeved. I just bought a nice 27" LCD HDTV and I'm ready to get some cables.
But, it's not worth the hassle of calling everywhere and checking (especially since they don't have any out yet), so I just ordered these from Nintendo. I have finally finished my initial wave of purchases.
It's really a releif to stop worrying about how I'm going to get everything and just play.
