Could Nintendo really hold on to all their hardware secrets until E3(or whatever blowout they have planned)? I know this is Nintendo we are talking about, but that seems like a real stretch...
Honestly when I said six months that was being modest considering GDC '12. Remember all the things Nintendo showed after they first unveiled Revolution? I don't because there wasn't really anything shown. We got the controller reveal at TGS, but that was about it for anything significant till the next E3. Maybe they'll throw us a bone in the next few months, but I'm not getting my hopes up for anything till around next E3.

I am going INSANE.
Also, what's the past history of Nintendo/other competitors' differences in spec between first dev release and final product? I'm talking GPU/CPU wise.
If the first iteration development kits of the WiiU had a supposed RV770 GPU inside, how much better do you think we'll get?
Especially now we're expecting 28nm... or are we? Is this 'rumour' likely? Will it solely be for the purpose of low power consumption?
Here is a link I posted a little while back for the PS3. Just scroll down some.

According to the poster and pics the first version has a 2.4Ghz Cell (final 3.2Ghz) and 256MB of XDR. The GPU was 430Mhz (final 550Mhz) and was a 7800 GTX. I didn't see any mention of how much memory the card had so I would assume 256MB of GDDR3.
Based on what I could find on the Xbox 360, it was an Apple G5 with a dual processor running at either 2 or 2.7Ghz (final tri-core PPE 3.2Ghz), 512MB of DDR3 memory with a Radeon x800 (my understanding is the final was a modified R500). And I believe the card had 256MB of GDDR3. It's also worth noting the 360 released six months after its E3 unveiling. So devs had way less time with it than they did with PS3, Wii, and Wii U. Makes me wonder if they'll try that again after the RRoD incident. But who knows they might try a 2012 release to still Nintendo's thunder.
Based on what lherre had said, there wasn't really anything to say Nintendo was going to use an RV770. I would assume what he said was based on paper specs Nintendo gave them, but that the first dev kit had a 4830. Considering the paper specs and that he said there was still info left out, it's pretty much up in the air right now as to how much better we'll see it.
I think the 28nm rumor is as likely as other things we've heard, so we would just have to wait for official confirmation. And the purpose could be to get the consumption as low as possible and/or bump the power.

The 28nm thing depends on if it was planned from the start. I think the HD4000-based guesses are still the most likely outcome and most credible(that's what the Japanese site gamewatch(?) reported shortly after E3 as well). The 28nm might be just for the MoSys RAM since IBM already confirmed the 45nm process for the CPU. 28nm GPU and 45nm CPU kinda goes against the "Wii U is a SoC-design" speculation and the people who checked out the LinkedIn profiles for the engineers who made the chipset in India were pretty certain that the Wii U chipset is in fact a SoC and not a seperate GPU/CPU setup. I still think Nintendo will just do a seperate GPU/CPU setup, HD4000-based GPU, 2GB RAM, PowerPC7 and you pretty much already have a system that outclasses the Xbox 360 and PS3 in every way.
I don't think it's possible for them to say, "wait we'll just throw in a 28nm GPU now!" without planning it well before designing the actual chips.
I know I thought they would copy the XCGPU to keep heat down, but this info changed that for me. I posted the LinkedIn profile link, but that was due to that 5+Ghz processor being mentioned not because I felt it was a SoC.
That said, to me with the investor mentioning both NEC and MoSys together gives me no reason to doubt that unless the size is wrong, Wii U will have a 28nm GPU with embedded 1T-SRAM. History is very strong to believe otherwise. I don't see any reason for it to be just the memory or why it would be important to mention the physical size just for the memory. I would believe saying the density or amount would be more significant.
I'm pretty much off the idea of the GPU even being R700-based unless we used a couple of aspects as the basis. And while I think the CPU is POWER7-influenced, I don't think it's cost effective to modify one for a console. It would probably be better to build it from scratch. I still think when it's all said and done we'll have a tough time categorizing the CPU and GPU under currently known categories. But I do agree that it will outclass PS360, even if it did just go with the first dev kit specs.
