The DS Lite is now two hardware iterations old. It launched back in 2006, and was a major redesign *of the original DS, from 2004. In 2010, Nintendo says it's not quite ready to part ways with the Lite.
"Our current plans are to continue manufacturing Nintendo DS Lite globally", a Nintendo spokesperson told website MCVUK. "The DS Lite has been a highly popular handheld console and has brought fun to an expanded audience of gamers — male and female; young and old — and sales remain strong. That said, it is true that our key focus in the UK for 2010 will be the Nintendo DSi and DSi XL."
The DS Lite will get support just like the Game Boy Advance did in 2005 or 2006. No, we imagine it will get less support. Why ever would Nintendo continue to support the DS Lite? The console can easily run R4-type devices that can be used to run pirated video games. The newer DSi would not initially run R4 cartridges. It has since been cracked, but the DSi has a layer of protection that just does not exist on the DS Lite. The DS Lite is the wild west, do whatcha like.
