I think the release of the 3DS might make DS games retired. Ever since the DS was released, GBA games became retired not to long after the DS came out and that might have been the reason the DS accepted GBA games. Another reason DS games might be retired is that since the 3DS plays DS games that might mean DS games will retire soon after it's release. When the Wii was released it was made to accept Gamecube games, months after the Wii's release Gamecube games became retired. It really depends on how many people that buy a 3DS to see if DS games are going to be retired.
