This is why it is good to have a team and more than one set of eyes looking at something. This information was spotted by Justin.

Take a close look at the two scans above, Monster Hunter 3G and the 3DS add-on, it clearly looks like the Capcom guy, pictured in the Monster Hunter scan, is the same guy demoing the 3DS add-on. If you remember it was Capcom who helped Nintendo develop the Classic Controller Pro.

Nintendo may very well be making a statement about the 3DS add-on later today. If not, we will have to wait until their conference next week.
