Turns out you were right! Yesterday, Nintendo announced another cosmetic upgrade to the dual-screened mobile platform, this time calling it the Nintendo DSi LL. Announced at a Press Event in Japan today, the DSi LL sports a 4.2 inch screen and comes with two styli, including a larger pen-sized stylus.
The new unit will come in three new colors, including Wine Red (ooh fancy!) and be preloaded with two Brain Training DSiware games and a the DS Easy Dictionary.
Reportedly, the pixels are the same in the screens, but due to the larger size, everything will be much easier to read. It seems to me like this edition of the DSi will sit alongside it, not replace it. The DSi LL could be pointed at the older market, or even more so as a personal device for more professional environments, like school or work. While this makes a lot of sense, I don't know how much of a market there is to be had, what with cell phones taking the place of so many personal organizers and the like.
The DSi LL could also be seen as a means by which Nintendo will be able to sell a DS to EVERYONE (something they have been striving for since the inception of the DS Lite).
