Currently the 3DS is looking like the PS3 of handhelds as far as launches go.
The assumption being made was that consumers would buy the new hardware simply because it was new, or perhaps simply because it was Nintendo, when the reality is that software sells hardware and currently there obviously isn't enough compelling software to sell the hardware to the early adopters.
I'll even argue that the best games to play on the 3DS are currently DS games, for which you do not need a 3DS to play.
Nintendo probably should have thrown out something other than NintenDogs and Pilot Wings as their initial titles.
Unfortunately since they just released Pokemon Black/White, that market's been tapped for the next year or two, but an exclusive Pokemon on 3DS would have moved a lot of hardware even though it would have been at the expense of upsetting a lot of Pokemon fanatics who would have to buy a new handheld to play.
Truth is, there currently isn't a single title on the 3DS that could be called a killer app that legitimately makes use of its hardware upgrades (specifically 3D) in creating an experience like no other that requires being played on the 3DS.
Until that happens it's just going to be a matter of slow adoption over time with sales picking up as the library expands.
