When the DS was relleased Nintendo was emphatic on the point that the DS was a 3rd tier and seperate to GB-GBC-GBA line. Where they just hedging the potential failure of the DS? Did the success of the DS and the explosion of the handheld market disuade them from devolping a new Game Boy? It's rummored that the WiiU was initially a handheld, did it stem from Game Boy development? Will there ever be another true Game Boy? What features would you like to see included or excluded in a Game Boy 4th Generation?
