Damn, I shoulda posted my blurb in here...
Essentially, the OFFICIAL line is the DS represents a new paradigm in gaming and is different enough that it will encompass a different overall market than the GBA has.
For many people, that is hard to believe...."a handheld is a handheld" and so forth, not to mention the unit plays GBA games...
Nevertheless, Nintendo has stated that development continues on the Gameboy Next, the real market successor to the GameBoy.
Altho I do beleive that last statement, I figure that such a device will likely not see the light of day for years.
The DS is Nintendo's new portable focus for the next 3-5 years at least...a "stop-gap" GB successor, only without the GB moniker...only if it does horribly ( which i doubt) will Nintendo rush the official "GB Next" to market.
So, in a nutshell, I dont think you have to worry bout that too much good Reverend...Im feelin the DS will be successful which will naturally push back the release of a GB Next for some time.
Hopefully, anyway. Like you, I dont want to see the handheld market go on a new hardware binge...
If I come across any links then I will post em for yas.
For starters tho, there may be info in the interviews conducted during E3...available somewhere on this site I think.
You can also check out Gamespy and Kikizo games for additional interviews...Gamespy has one with Miyamoto-san and a Nintendo hardware designer, and Kikizo has one with Satoru Iwata. The last one is proll the better place to start...
