Nintendo say that Enterbrains beliveable new DS prediction is justquite plainly not true. 

"We cannot comment on the specifics of what will be announced at E3, but at the very least there won't be anything like what Mr. Hamamura suggested, so would like to clearly deny this. We're having a hard time understanding what kind of evidence [Mr. Hamamura] had for saying this."

There you go then, Nintendo say that there's not going to be a new DS. A new Game Boy perhaps? You never know with these guys...

But of course, they said that they wouldn't remake the DS in the first place, then brought us the DS Lite. So y'know, this could be another white lie.
