"Music player function.
Exchange data using SD cards (integrated slot?)"
If those two would be there, the DS would be SoftModded within a week tops.
To be fair, Piracy is up to about the same level on the DS already, a revision wouldn't affect much.
Interesting rumour, this certainly came out of nowhere, and it would certainly explain why Nintendo feel the need to hold two consecutive conferences in different regions this week. T'would be an important announcement.
Whilst it is hard to say if any of this is true at this point, the new rumoured features certainly sound plausible. Nintendo have already experimented with Cameras and MP3 players on their handhelds, so they'd be easy to stick on.
Whilst Larger Screens might mean a necessary upscaling on older DS games, if the GB Micro could shrink the screen size of GBA games and still render them completely playable, I can see the same kind of thing happening here. Can't say I noticed any problems with the wireless functions, but if they want to give them a boost, then fair enough.
The SD card slot feature is the one that interests me the most though, could it be this that finally allows for a Portable Virtual Console? Of course, it's probably just for the Photos and Music storage, but one can hope. Transfer all Wii-downloaded post-N64 VC games and play them on the move? Yes please.
Even with all these added features, Nintendo could just release an add-on for the DS Lite/Phat for Camera/Music/SD for current users as not to render them obsolete.
I can see a lot of truth in this one.
