The latest issue of EGM stated that come May DS Lite will be unveiled in U.S. Officially no reason has been shown behind selecting this very date but may be, yes, may be Lite will with intent be launched on this time so to coincide with the release of New Super Mario Bros.

Seems rumor only but the question is will EGM write an investigative (or properly sourced) article like this without any concrete reason?
