My wish would be that they wait a few years, get their hands on some new tech and make Fallout 4 then. I love all four (1-3, NV) for what each of them are and I do not need another one released just to do so at this point. I would rather see F4 released when there is more of a reason to do so, rather than it has been a year or two and we need to try to capitalize off of the brand as much as we can.
