I'm guessing he will not run all out. He will be a good 10-25m ahead of everyone by 250m and will also start to feel tired around there, so he'll probably "jog" the last 100m. I'm guessing a 45.x.
I saw Tyson Gay split a 47high/48low in a relay in 2007 or 2008, and he looked like he was not enjoying himself, though he was clearly not all out either. I think Bolt has more potential at 400m than Gay does though.
Your right I don't think he cares enough yet to try for the entire 400.
