Is it crazy? Yes
Is it unlikely? Yes
Is it pre-emptive? Yes, wait until after Nintendo's E3 conference.
However, is it impossible? No.
There's more competition now than for the previous set of handhelds. Unless Sony really push it like Kinect last year, it's easy to say this will sell even worse. AND its early days for the 3DS yet (infact, the update today proves that; i'm using it to write this!)
Remember, the 3DS was gonna be out in 2010 initially with loads of games at E3. That didn't happen. We've only just seen the conference. So, it's a bit early yet
