You have to consider the amount of content that would need to be produced to make that game that size. It may not even have a human developer, as it would take a large amount of time.
There's going to come a day when robots are the developers of the games we play. So, I'd say 60-75 years until we get a 1TB game.
The Robot who makes that game will probably do it for the sake of saying it made a game that's 1TB in file size. Let's hope it's a good one. It might.
