A couple things:

-The size of these screenshots are hardly an indication that the game will be HD

Agreeed


-Current Wii games render at 640x440ish according to Quaz51.

Actually some games run at 800x480.


-The hardware in the Wii might not allow for HD output. I'm not talking about having the horsepower to run in HD, I'm talking about having a DAC (digital to analog converter) capable of handling HD output. So even if you just want to output a simple HD picture, the Wii might not be able to do it.

Did the ps2 have this DAC? I don't remember it having one. Actually I didn't even remember the original xbox having one.



-Rendering to the GDDR3 RAM is slow I believe. At least that's what I gathered from reading the Beyond3D thread about the Wii.

It's the same speed as if you to render the integrated 1T-ram. It's been stated so many times.


Which games run at 800x480?  Do you have proof/links of this?

Sorry it's only  783x444.

ALL consoles have DACs.  That's how they output their signals... CPUs are digital, most TVs use an analog signal...

Well I'm guessing if the ps2s and the original xbox supported this the wii would too. We don't know for sure I guess. 

Do you have links for your last statement?  "If I remember correctly, you can render to the main memory directly. It would be excruciatingly slow and thus useless in any reasonable scenario involving gaming, but rendering a higher (than what the 2MB eDRAM could hold) resolution framebuffer might be done theoritically."  That's from the Beyond3D link.

"
Wii uses 64 megabytes of GDDR3 (MEM2) as external main memory. Like internal main memory, MEM2 can be accessed directly from Broadway and the GPU at high speed and has a peak bandwidth of 4 gigabytes/sec. Programs can also be placed in MEM2.

Reference Information: Nintendo GameCube ARAM is used as auxiliary memory for the DSP. The CPU and GPU did not have direct access to it."
