So, lherre is hearing a bunch of stuff, and he only has an impression that no one is working on it outside Japan. Whatever is going on, lherre seems to be out of the loop.
Also, lets clarify what the others said:
Emily w/NateDrake backing up her sources: Closer to XBO than PS4, but even that is a stretch. Nothing else to clarify what that means. Architecture is NOT AMD. Hints to be Nvidia.
NintendoWorldReport:: Close to XBO.
Alberto: Don't have any inside info about power AFAIK. It should be noted that his "sources" let him down big time recently with that fake controller.
Thomas/lherre: Appears to be out of the loop atm. Heard crazy stuff, but doesn't seem to be solid atm.
Don't forget LCGeek's comment and OsirisBlack's comments. Also wondering about KawabataSan. Would be interesting to see if he gets verified, because his statements dont't match those of Lherre.
Also, Alberto has been too wrong too many times for me not to ignore.
