5. Project H.A.M.M.E.R.
Last Seen: E3 2006
Actually one of the more promising trailers for the Wii, nothing has been heard of Project H.A.M.M.E.R. since 2007 when all Nintendo would say about it is that it was “on hold”. It would be very surprising if this came out of the vaporware pit at some point as it would have to be completely re-worked for the Wii U and Nintendo probably thinks their money and resources would be better spent elsewhere.
