I was at the auto show today and they mentioned a new "high torque" CVT which I think will be in the Legacy to handle the power of the V6. So I would think that it is a pretty good likelihood it will happen.
Yes CVT will be sold on the 3.6. In manual mode a review noted that it had 8 simulated ie manually selectable gears of course with a CVT the CVT has far more gear ratio options than that. But pretty sure Subaru opted for 8 simulated gear options for the 3.6
