I was just thinking that. I wonder how many other studies there are currently underway that aren't specifically looking at the ME/XMRV link? Did anyone know of this study? The four year question was just because they began this study in 2006 (imagine how hard it has been for them to keep quiet for all this time). It is a wet fish in the face for McClure and Wessely. I thought Coffin suggested 50 years, didn't he?
