Most likely, never. It seems he has moved on to MMA. Brock still seems like he likes Wrestling because he talks about it still, but since he is the UFC Heavyweight Champion right now - it would be hard to believe he would go back to WWE again. But nobody can speak for Brock expect Brock, so it is always possible.
As of now - Never. Brock Lesnar is no longer with the UFC. He retired from UFC at the end of his last fight with Alistair Overeem in 2011 and is not expected to return to UFC in the near future. He is currently with the WWE where his contract runs till 2015. Due to his health situation he may not consider returning to the UFC
It is predicted he will make his return to WWE at Night of Champions and he will tag team with Chris Jericho as the as either the American bad ass or some type of new alter ego. Its all put together.
