I don't see them using a text interface, seeing as how the series dropped it at KQ5 and the fact that it would hurt its play on consoles. The thing I worry about is KQ losing its large open world feel and instead it would have the few areas you jump to a la Sam & Max.
I finally built a working time machine! It's not perfect yet though, it only moves forward in time and it's a bit slow. You have to be in it for one second for every second you want to go into the future.
