New information as of 06.06.04:
3d renders directly to lcd, no framebuffer.
2d is handled by gba hardware, also in ds games.
arm9 has access to framebuffer when using bitmapped 2d modes (gp32 ports?)
lcd is 6:6:6, vram is 5:5:5
3d is handled 100% in hardware. (yay!)
supports z-buffer, w-buffer, stencil-buffer and anti aliazing
touch-screen is functional on dev-units, wi-fi is not. (no wi-fi libs for devs yet)
carts are matrix memory 3d technology (http://www.matrixsemi.com)
you fetch data into a buffer, then read from that buffer.
It has two 2d cores, so you can effectivly have one gba on each screen if you do not want to use 3d. (one 3d core)
Dev units does not do gba games yet.
Nintendo has a full blown pc emu. (no is-agb stuff, just plain emulation. Source level debugging with cw)
Devs do not have pdfs of the new non-gba features, only paper-documents with large reg numbers on them. (alteast the one I talked to.)
The carts now have a file-system, propriarity.
DS will have two cart-ports, one for GBA and one for DS games.
DS games are (atm) about the size (physically) of an sd-card, a little thicker.
No GBA link port as of yet.
Questions unanswered as of now:
How do you split tasks between the cpus?
What part of the 2d hardware is modified, compared to gba?
Thorough check of the specs below
Does the 3d hardware do alpha?
perspective or affine tmapper hw?
soundchip?
what extensions do the arm9 support, and does it have a math co-processor?
Texture filtering?
Mipmapping?
Trilinear filtering?

Voilà qq nouvelles infos ........ pour l'anti-aliasing ça parrait bizarre compte tenu de ce qu'on a vu des démos de l'E3 (la question est aussi posée pour tt ce qui filtrage de texture divers ^^) ........ et aussi sur le µP graphique (inclus ou non dans l'ARM9 ou comme certains le pense un "ATI Imageon 2300" même si ça parrait peu probable ^^).
Je veux des vrai niveaux!
