Nintendo had a choice, just like MS with the Xbox, and they chose to end production for the GBA and focus solely on the DS. They could've waited if they wanted to, Sony could've launched a new handheld in 2007/2008 when it looked like the PSP was all but done, but they didn't. Dismiss deeper context? What are you talking about, there's no "deeper context" here. Like I said, the GBA would've sold more had Nintendo not ended its production early to get the DS up and running, but they chose to end it and that's that. Using that as an excuse if/when the PSP sales surpass it is foolish IMO. To me, it's akin to saying Karl Malone scored more points than Michael Jordan, but MJ has a higher PPG average. Irrelevant because Malone still scored more points and kudos to him for being able to play longer at a high level.
Anyways, this is completely OT, so I'm done with this subject. I just wanted to share my opinion on it.
