Well architecturally the CPU could also set them in good stead since its design seems much more in-line with other next gen console CPU's. Which is almost certainly why some developers have had problems with porting code from current gen. Optimised code for one kind of CPU can be unoptimised to another kind and WiiU's CPU doesn't have the raw power to overcome that. But that isn't indicative of how well the CPU can handle code from other next gen console CPU's. For instance Nintendo could have used something exactly like Xenon and no developer would have any problem porting 360/PS3 code without modification. But that certainly wouldn't be good for future titles, as next gen console CPU's are going in a different direction and Xenon would be a total fish out of water when dealing with code optimised for those kind of CPU's.
I think WiiU's design is focused on next gen development, which is certainly a good thing IMO despite it being to the detriment of some current gen porting. But I do agree that its a pity they couldn't see past the whole console size issue and hike the clocks up a bit.
I posted a reply earlier regarding the CPU being a weak point in the ports of PS360 and was hoping to get a response from those that have sources. Unfortunately, I think the post was overlooked. It would have been nice if the size wasn't holding back the clocks, hw, etc...
That said, is it possible the CPU in the Wii U will be more powerful then what the developers have access to currently? For example, the 3DS had power that dev weren't able to use because Nintendo was overly conservative and set aside plenty of resources for the OS features. I'm sure Nintendo is once again being conservative regarding what resources are set aside for the OS. Nintendo seems to traditionally be conservative in these area's and considering the rumors we've heard regarding the amount of RAM the system has set aside for the OS, doesn't this seem likely or at least feasible? I don't know if there was ever confirmation of how much power the 3DS gained after Nintendo freed up more resources, but rumors at the time suggested around a 25% increase.
Could there be a similar situation with the Wii U's hardware and specifically the CPU? Example: After a few months Nintendo is either able to further optimize the OS and features or that they were overly conservative which leads them to feel comfortable with unlocking more power for dev? If so, that may explain the rumors that the CPU is "weak". Even a small increase in power regarding the CPU should put it "over the hump" in regards to PS360 ports I would think. A game like Assassin's Creed should be pushing PS360's resources. If a Wii U port of AC3 is at least "on par" then even a small increase in the Wii U CPU should make other ports easier and require less optimization of the code, correct?
Obviously, this is just speculation but I'd like to hear if anyone with sources or with a lot of Technical Knowledge thinks this is possible, likely, unlikely, etc...
