Patents with three popular telephoto lenses with the addition of image stabilization have shown up. It's long been expected to see IS added to Canons highly regarded 135 f/2.0, I don't know where a 2.8 will fit into the lineup, and adding stabilization to the 85 and 100 would follow with Canons current practice of sticking IS on all their mid-range glass.
