Didn't Nintendo say that the 3D effect works better when the inside of the top screen is black?
I wonder if this change will have any effect on the 3D quality.
Honestly, the 3DS XL looks like it was redesigned to fit with the WiiU if and when they would like to do a FourSwords Style interconnect. If you don't have a extra GamePad, and have a 3DS/3DS XL, just sync it in. Hopeful dreaming, but still...
