DSi Miami...
*cough* sorry.
I, personally, think that the cameras is a VERY BAD IDEA.
Sure, the eyetoy like fun for games would be neat, but think about the children! *Sad music*
Moms are gonna go nazi on Nintendo and accuse them of encouraging child porn or something like that. And I assure you, with wifi and the camera, people can and WILL abuse it.
...besides that, the DSi is sure to be super expensive o_O like $200.
