Project spark is also using voxels
Here is a link to an IGN post that I believe selnor is basing his thread. Very interesting read. Need to go to the bottom for the X1 stuff. From MS build event I do remember that it was stated that the X1 has hardware based tile rendering which was talked about before. Combining that with voxel cone raytracing might produce some very interesting results.
