Doing some searching as I wait for Asus to release a new version of the G46VW..... I came across this.. The motherboard is clearly labeled "G46VR REV 1.0" I also noticed a couple things; one being the traces for the thunerbolt chip are not longer present as they were in ALL revisions of the G46VW motherboard. (pictures below) Also, the GPU die seems to be a bit larger than the G46VW. Can't make out what the chip says but I'm also temped to buy this since it looks like the same exact layout as the G46VW. Another thing, the mSATA slot has 2 posts and the ITE (Embedded controller) is between the two posts. This is clearly another model motherboard all together.
EDIT: ooops here is the link I found it at
