I know they won't, but wouldn't it be nice if Bethesda made an official version of TTW
Here is what it would entail, work with the TTW developers to get further TTW things done by Bethesda's developers, incorporate the Fallout 3 and New Vegas bug fixes into the ESMs, add a few of the Fallout 4 graphic updates, change the EXE to 4gb (like with Skyrim), and release it for PC and Next-Gen consoles as Fallout TTW, sell it for 30 bucks, and make is so that if Steam detects both Fallout 3 and New Vegas on your computer it only costs 20.
I would buy that, and it would give a tremendous incentive to Fallout 3 (script heavy) mod makers to make TTW versions because it is official from Bethesda. Bethesda makes money off limited work, and Obsidian makes money off their deal with Bethesda for no work at all
It seems like everyone wins, alas it will never happen
