Just thought I'd throw something at the wall, a suggestion from an old fan of the series.
This is a great idea, I don't know why they haven't already done it, I would buy an Elder Scrolls Anthology on my Xbox one, and I certainly would play Oblivion and Skyrim on it.
There's already ESO on next gen which is pretty good at the moment - a lot better than the 2014 release and the sub was scrapped last year in favour of buy to play and DLC - and has a lot to do, though that needs PS+/Xboxlive. Having the others on next gen would be nice, but a lot more work than you think. Also, the source of Arena and Daggerfall were supposedly lost, so they can't easily port those two, which already would require significant work to get them up-to-date)
I just want a Skyrim re-release, I would be soooo happy would play until next ES easily. And quite honestly its feels like one of there more "complete" games, the amount of gameplay and questing was sheer greatness that I would gladly pay again for. Do you hear me Bethesda I will not embrace the great darkness.
Bethesda games on the PS3 might need a remaster because they are broken and Sony refuses to add backwards compatibility . The XB1 just needs backwards compatibility
