There's this Game Boy Micro:

And two DS...es:

And guess what? There's a total of
SEVEN Game Boy Advanced SPs!
(because of length, I'll just list them, that and I can't find their images...)
Game Boy Advanced SP Torchic
Game Boy Advanced SP Groudon
Game Boy Advanced SP Kyogre
Game Boy Advanced SP Charizard
Game Boy Advanced SP Venusaur
Game Boy Advanced Sp Pikachu
Game Boy Advanced SP Rayquaza
There's plenty more:
Gamecube with Limited Edition Shadow Lugia Faceplate
Game Boy Advanced Pok?mon Center Edition
Game Boy Color Pok?mon Gold/Silver Edition
Nintendo 64 Pikachu Edition
Game Boy Color Pok?mon Yellow Edition
There might be more (a.k.a. different countries may have different editions), but these are the systems that I know that have been released in either the US or Japan. (the Rayqyaza and Pikachu SPs, both the Nintendo DS...es and the Game Boy Micro are or were only avalible through Japan as of yet...)
*EDIT*
WHOA!!! I just learned that the Nintendo DS Pok?Park 2005 Edition has been released in the US! It's only through Wal-Mart, so you guys better start saving!
