Nintendo has had less revisions (AFAIK) of the DS than Sony has had for the PSP.

Only two DSs: NDS and NDS Lite.
PSPs have had 3 versions: PSP-1000/2000/3000.

Granted, the GBA had three (GBA/GBA-SP/GBA-Micro) and 2-3 classic GBs: Game Boy (Heavy brick of a 4xAA devouring monster, indestructable) GB-Pocket (awesome 20 hours on 2xAAAs) and later GB-Color an updated GB classic, but I digress.

The DS has been kicking it since 2004. Five years ain't a bad run. I myself am excited that there will be two new Nintendo systems in the next two years B-).

The UK gets shunned by Microsoft on a price cut when it does finally get here they'll announce another 1 for the rest of the world.

Its a panic by MS because of the x-mas period apart from GEARS 2 and Fable 2, Fallout 3 what else have they got coming out. It will sell well thou still think the Arcade should get the 20GB HDD with them and Premiuns 60GB, Elite's 120GB seems more sense really.

And why Nintendo keep releasing a new DS every 3 months is beyond me are they just going through old design plans till the 1 they wanted has been found on the pile.
