If, at any point in the last week, you forgot about the existing DS platform due to all the news about the 3DS, you've made a serious error, and you owe the Nintendo DS an apology. Nintendo brought a diverse selection of first-party (and sorta-first-party, in the case of Dragon Quest IX) DS games to E3, and we've collected trailers and artwork for the whole set.
Included after the break is Professor Layton and the Unwound Future. It might be a little ... puzzling, but Nintendo brought two Professor Layton games to E3 (which means, by the way, that this was the best E3 of all time) -- this one, number 3 in the series, for the original DS, and Professor Layton and the Mask of Miracle, which is number 5, for 3DS.
