Has anything like Game of Thrones (and live action) actually been rebooted? There's a massive difference between ASoIaF with it's very specific, complicated plot and such compared to loosely taking the premise of some 30 year old procedural into an essentially new show. Or comic books taking the origin story but using another villain, another author's take on the character, etc. I don't think we will be getting GoT sci-fi, modern day, etc. version or something obviously. Although hey, wouldn't mind watching a pilot for that.
Creating another relatively loyal adaptation that doesn't diverge after ASoS would be so many hours of similar, expensive material to recreate with limited appeal before you get to the real changes with no guarantee it's popular enough to get there. If it was an anime and you could just use the same voice actors/art style and pick up from halfway maybe in some format but doing that with a new cast? Eh...
I bet it's just spin-offs until audiences lose interest for a very long time. Maybe someone tries an ill-advised film adaptation.
