I hope no one is seriously making that argument. The difference in RAM alone opens up what developers can do by a significant degree.
I remember one game designer last gen talking about how they'd come up with ideas for an encounter only to have the programmers come back and say, "nope, this can't be done, there isn't enough memory," and they'd have to change the event or scale it back. I believe it was the developers of Dishonored who said they kept having to cut down levels and remove enemies to make things fit on last gen consoles.
There will be games this gen that cannot run on last gen hardware without large-scale changes to game-play. I'd be shocked if anyone seriously disputes that.
