Ben is a smart dude , lot's of business savy learned from being around Mladdin so long.
He has unfinished business in GP and can possibly make a statement there with Ducati ( what they can deliver is the big question in my mind) .
He realised that taking a second string ride with someone else in GP was not going to cut it, probably spent some time talking with Colin Edwards if he is as smart as i think he is.
Going back to Superbike is a great fall back position if Ducati fails to get the bike right. Wonder how long his contract with them is for ??
