I actually think this article is the first time he's being 100%, truthfully honest. He wants to play this season out, to see what the Nets are like.
On the slimmest of slim chances that teams play harder against the Nets now, causing them to struggle to run (which won't happen. The Nets can run no matter what the other team does) combined with KMart and RJ not improving in the halfcourt (which again, won't happen. They're too athletic and have incredible work ethics), AND combined with it not looking like they'll eventually sign KMart/RJ (again: won't happen): Maybe he'd leave.
But again, those things won't happen (knock on wood), and I'd be very shocked if he was elsewhere next year.
