Nintendo starts pre-orders for Play-Yan video adapter

Remember when we told you Nintendo would be adding video playback abilities via a $49 adapter for the DS?  The company is now taking pre-orders for the device,
called Play-Yan, and it is, in fact, selling for $49.  It is also listed as being compatible with the SP.  In addition to playing both ASF and MPEG-4, it will also play back MP3 files.  It will use SD cards for storage (up to 1GB), and battery times are currently posted at 4 hours for video playback and 16 for MP3.  Other devices do already exist for video playback, but a Nintendo-made one can't be a bad thing.  Can it?
