Presumably that's in reference to lherre and Arkam, although I think the latter is an engineer rather than a developer?
If it is those two, then do you know which companies they work for, and what the two of them said, definitively, about the Wii U's final specs? I'm not talking about things like cosigning dev kit rumors, directly or indirectly, or making nondescript and vague generalizations, that don't tell us anything of real relevance, like "enhanced Broadway". I'm talking about them actually saying something like "These are what I know the final Wii U specs to be.", from having direct access to either the final DK or the retail unit, and then stating those specifications.
Knowing exactly which developer they work for is very important simply because some developers are not privy to the same classified information, and the most recent dev kits, that other dev studios, whom Nintendo greatly trusted, were. This is the reason why we had seen conflicting reports from anonymous devs and named devs, who were confirmed to be working closely with Nintendo.
I can imagine that the developers, who were not trusted enough by Nintendo to have certain privileged information, and, in turn, had to settle for older less capable dev kits, weren't all that happy with Nintendo. Probably for good reason. More than likely, they didn't mind expressing their disappointment in the hardware, in which they were forced to work with, as an "anonymous" developer source. Developers are human, and it shouldn't be all that surprising that some of them may result to such actions in order to deal with their individual frustration with Nintendo appearing to treat them as second class developers.
It is because of this, possible and even likely scenario, that I never gave much credence to anonymous developer sources and neither should anyone else. So it becomes exceedingly relevant to know which company a source works for and then understand the relationship said company has with the console company they are commenting on. This applies to PS4/720 as well.
