As rumors continue to grow concerning changes in the final specs for the Xbox One, a member on the website Beyond3D speculates that Microsoft is actually asking developers about an increased GPU upclock and a increase in total DDR3 RAM to 12GB.

This is not the only rumblings that the final hardware specs are still up in the air for the Xbox One apparently Engadget was able to get a inside look at Xbox One development a few days before the Xbox reveal which is around the same time beta devkits were sent out. In the picture above you'll notice many variations of hardware design leading to the idea that these might also contain different variations on internals that are still being tested even days before the reveal.
