G-rank quest are specifically designed to go with titles bearing a G. It also acts as an unofficial symbol for the last game of its generation. (Apart from MHG, MHP came after MHG and was the one and only title to appear after a G-titled game, that's unless you count in the Wii version of MHG.) So if MH4s reception is great and Capcom feels damn satisfied, yes, I'm sure there is going to be the possibility of a 4th generation G title.
