I just saw this sucker on a page at gamestop.com. BTW, they are the semiliterate ones calling it a "lite", not I. See:

So does anybody have any inside info on this? In particular, I'm wondering whether it has an on/off switch, or if it is a continual powersucker. From what I've read about it at gamefaqs, it plugs into your link port and replaces the stock screen. There seems to be some uncertainty about whether there's a pass-through for your link port, as well. For $40, I want features, dammit!
Edited to remove excess usage of the word "sucker".
