There is a new rumor floating about that a couple new colors will be making their way onto the DS Lites. This pretty red and green have been shown as coming soon on a Spanish retail site.
Which hopefully will mean those of us in the US will have shiny new colors to salivate over. The Spanish site is supposedly the second largest gaming retailer in the world, so if they say it is coming soon, odds are it's fairly accurate.
Apparently they will be hitting the site on June 13th so hopefully right around then we will find out good news for those of us in the US. You can't ever have too many choices for color, so the more the merrier.
