I'm not convinced at all that they can come up with a way to work this where right of first sale isn't ruined and, as such, the whole concept of ownership. I don't anticipate this going anywhere.
That's sort of the thing, GOG can do that because the games are DRM free and there's not really any way of GOG taking back copies other than to physically come over and delete them for you. For the cost of even the most expensive title on here it just wouldn't be viable.
But, when it comes to hard copies and discs, those absolutely should have an absolute right to resell for whatever one can get for it.
