I would think if it was going to be out before xmas, we would have heard about it by now.
If you're willing to pay for it, you could import a Japanese one. DS Lite's aren't region locked, it uses the same plug/voltage, you'd just have to set the language to English the first time you turn it on, it would effectively be the same as one sold in the US.
Or, get
this. I'm thinking their picture is BS though, I don't see them sending you color matched buttons and D-pad.
