I watched a movie on GameSpot about this. The Nintendo guy said that he didn't want the DS to make the SP obsolete, and that they would still make games for it. He just thought that if the DS could play GBA games, it would sell better. He didn't want it to play GB and GBC games because that would, as stated earlier, make the GBA obsolete.
There is no ''I'' in team...Nor is there an ''I'' in group, gang, crew, squad, club, band, party, crowd, cluster, troop, or set.
