All wrong.
There are:
Last Last Gen: N64,...
Last Gen: GC,...
Current Gen: Touch, Wii
Next Gen: Xbox1080...etc.

Last Last Gen + Current Gen = Last Last Gen

andere Aufteilung mit Touch als Next Gen:
Last Gen: N64,...
Current Gen: GC,...
Next Gen: Touch, Wii,...

Last Gen + Next Gen = Current Gen

ergo DS Lite = Last Last Gen
oder DS Lite = Current Gen

you choose.
