Well I've already pre-order the Nintendo 3DS and I'd highly recommended that you go forward with picking up the Nintendo 3DS at launch. Although the launch library isn't as strong as some would have wanted it to be I think it's still solid.
Two of the best launch titles are Cave Story 3DS and Super Street Fighter 3D Edition.
I'm sure that in April there will be even more great titles that Nintendo hasn't yet acknowledged.
If I were you I wouldn't pass up the Nintendo 3DS at launch. This is a revolautionary device and it's great to be apart of something like this in the dawn of it's launch.
