Because the new console requires installation vs. disc play, would this allow the possibility of PC mods or maybe a construction set to be used with the next console version of TES?
OR
Perhaps TES Online?

mods not being on console has nothing to do with installation/disc play.

Its because Sony/Microsoft/Nintendo will NOT allow it. it is against their EULA and if a dev made the console version mod-able, would not allow it to be published, and may take legal action.

you will never get mods on a console within the foreseeable future. period.

if you want mods, go invest in a gaming PC instead.
