Hi!
I don’t know if you know the following sites:
You can find the KQ1,2 and the Quest for Glory 2 remakes here: http://www.agdinteractive.com/.
The KQ3 remake can be found here: http://www.infamous-adventures.com/kq3/
and the KQ4 remake can be found here: http://www.waywardmind.com/KQ4/
The KQ4 remake site is kinda empty but more content will be put up…
All of the mentioned remakes have been done by fans and are very, very time consuming so I don’t think there will be other remakes with more current technology.
But you can start with those 
Happy gaming!
