I've stated why I don't think they would, and it's because Bethesda has already been successful with previous Open World games, so that's what they will probably stick with.
The flaws are many, how many times would you be able to kill an enemy, would you be able to return to a previous location, how would we explore (there's a small set location, you wouldn't see any iconic things really, roads, billboards things that make up canon
) the list goes on.
The reason it worked before is because there was no other system back in the day, now we have better technology for open world sequences. And if I recall, Node Maps weren't all that successful before, they weren't unsuccessful, just not as successful as games nowadays.
Back in the late 1990's, Fallout was good (for a little bit). Then an epic little game called "Diablo 2" came along and blew people away. The node map system vanished after that, in all honesty.
when you are one the world map you chose a grid you want move there and depending in what grid you are the games loads the right height map textures and populates the map with rnd stuff.
So if you hold an a street the game lets you spawn on the street and get your billboards and gas station maybe some house or police station with diner whats common. The map could be the size of new Vegas. you go and look up whats in the police station read from the computer get some trash maybe find some geckos or other animals. if you saw all you want you go back to the world map go somewhere else like some huge city grid you spawn there and you get something similar to DC in F3 you can enter some building or go to the sewers and back to world map. the hub nodes are persistent no rnd stuff spawning just that what the Dev′s think its right for the place.
In this state like tes games are after you saw every thing and have all locations. The world is Dead! With the world map you have always something to do to RP, scavenger or play a gecko Hunter somewhere in the hills looking for theme. What you are thinking is moving on rails. But this not the case. You know why F3 and NV end after the last quest? right the game is dead nothing to do. You sad you like D2 so its not so different with the nodes. You have in D2 in Act1 the hunter camp and if you leave it the game is generating a rnd map when you reach akt2 you have the desert city that’s always the same. So the City’s stay and the only difference is a loading screen when exiting the world map.
The benefit is that consoles can have much more objects and your memory don’t gets flush t with millions of objects + AI and and and. The rnd wasteland areas matter only for the time you are in them when you leave theme they get delete and if you enter a new rnd location there will be a new generated area.
For mod makers its even bather to add new locations like City’s, quest areas, that fit in the existing world now its like two city’s each 200 meters away from each other and if moder wants to add a new one its getting even more cramp t.
For me is the node system a huge replay value, loot surse, unending combat and RP possibility.
Its like wandering the wasteland and not beaming thru areas.
