Not if we go by the historical record. The EOS-3, as I seem to keep repeating here, was essentially a vertical grip-less EOS-1, same 45-pt. AF, shared the same motor drive and battery pack, and had one feature absent in the EOS-1v: ECF. So if Canon would use that model name on a DSLR, expect it to be a VG-less 1Dx, maybe just 8FPS gripless, but would retain most of the other features of the flagship model. In short, it won't have those specs and won't have that price.
