True, you've already got a pile of old DS games (and now defunct DS devices) that you could be playing on your new pedometer, but more than 30 three-DEE titles are expected to be released during the 3DS "launch window" (which begins March 27 and promptly closes on June 7 with the start of E3).
We've listed 24 of the apparent launch-window releases after the break (though Nintendo's being coy about exact dates), including Nintendo's own Nintendogs + cats and Pilotwings Resort, plus a hearty helping of third-party support; with notable newcomers, Shin Megami Tensei: Devil Survivor Overclocked (previously unannounced outside of Japan) and Crush 3D, a possible port of the 2007 PSP platforming puzzler from Sega.
Don't look at the date ambiguity in dismay -- see it as an opportunity! Beginning in late March, you can walk to and from GameStop in anticipation of a new batch of games each Tuesday for ten whole weeks, and the 3DS will count your steps -- each and every one of them! And just imagine how many Street Passes you're going to rack up?
