Here is a ms patent

WIDE FIELD-OF-VIEW VIRTUAL IMAGE PROJECTOR
...
One these patents became available today another referring to determine depth using lasers referenced what MS calls a "three dimensional gpu". This my first time seeing MS referring to a gpu in such fashion.
To be honest if MS releases a console with 3d lenses that projects a illumni room like wide view while projecting 3d images that appear as if they are within your living space and it works well. Its a wrap and the lack of gpu performance wont matter.
Given my experience with 3D so far, I would have to disagree entirely.
