Remastered versions of the games on consoles would make Bethesda a mint just like Skyrim:SE did, and they have all the resources they need to do it.
This wouldn't affect Skyrim as much as all the music was composed for the game and most of the voice acting was done with Bethesda staff or using professional voice actors like Charles Martinet who would have had a contract more open to re-releases/remasters. It's entirely possible that even Zenimax is having issues with the SAG and RIAA and it's not worth the extra money to pay these actors who are now even more valuable than they were back then. Both the Capital Wasteland and F4NV fan remasters have received warnings from Bethesda that they would be running into legal issues with the game's voice acting and music, not from Bethesda but from the SAG and RIAA which stalled both projects. Their contracts may not have allowed for their voices to be used beyond the initial release. You have screen actors like Ron Perlman, Malcolm McDowell, Liam Neeson, Matthew Perry, Wayne Newton, Kris Kristofferson, etc. I think a major problem may be licensing for the game's voice actors and the various music used. It may not be as simple as the resource issue.
