Today Nintendo launched the Nintendo DSi XL system in North America. The new Nintendo DSi XL is available in Burgundy or Bronze for $189.99 MSRP each. This is pretty much a larger version of the dual-camera Nintendo DSi system. Some features, besides the obviously larger screen sizes, that stand out on the Nintendo DSi XL versus the DSi are two locking viewing angles, louder/crisper speakers, a larger stylus, 3 additional DSiWare games and apps included, and a glossy top outer panel with matte bottom panel.
