6TB is just so over the top. Even of the console was 6-7 years away to allow the PS3 10 year lifecycle to come to play there is nothing conceivable we can output that would require more storage on a single disc than ten home computers' full storage capacity put together.
I call shenanigans on this one.
And what about drives and processing units? The hardware required to make full and good use of so much information is beyond any of our imaginations at this point and certainly won't pop up within half a decade.
