I'm taking a stab at the main components of what is in the dev kit:
- AMD Phenom II x3 (maybe x4)
- 1GB DDR3 memory
- ATI Radeon HD 4870
I chose these parts because they seem like they could represent an early dev kit based on what we know so far. The CPU and GPU in their respective lines have higher wattage outputs which could generate the heating issues (although the latter is also me being hopeful). The CPU has 6MB of L3 Cache to give a slight representation of what they are getting from IBM. The reason I went with "only" 1GB of memory is because the off the shelf 4870 would have its own memory (which I believe was an unintentional mistake in the IGN test model). If say they were using a 4870 with 1GB of GDDR5, then the dev kit has a max 2GB of memory to access, and would be inline with one of the Ubisoft's guys comment about a large pool of memory. I'm still hoping the final version will have at least 1.5GB of GDDR5 memory. I'd like to believe the devs talked Nintendo into a higher amount than what was rumored. Although I wonder if the latency in GDDR5 is bearable enough to use it as unified memory. Anyone have a deeper explanation for GDDR5 latency and the effect on a CPU?
I agree with these points, and would love to see it happen if it would also allow Nintendo to squeeze a little more power under the hood. The thing is those same points you use to justify that route are the same reasons why they more than likely won't go that route. Why go against the grain of what's been profitable for you all these years? The loss they took on the GC at launch was supposed to be extremely small, then they took another "bigger" loss during one of the price cuts after not selling well. I'd like to see them do it as a consumer, but their business practice says that we shouldn't get our hopes up for it.
But that's not even logical. You're essentially saying that not only will no non-gamers/casual gamers that bought the Wii will buy Wii U, but some of those who bought a GC won't buy one either. The Wii U will sell more than the GC just from name recognition alone. I don't expect it to sell as much as the Wii right now, but it's not going to fall off like that.
