I'm not sure, but I'm going to make mine flexible. I'm going to attach little adhesive velco tabs to the unit then put two more velcro tabs on my TV both directly below the screen and directly above. If I'm standing, I might get a better response from it if I place it above, or if I'm sitting, I might get a better response by having it below. It'd take like 2 seconds to change up.
That said, based on that new IGN footage of the system settings, it looks like it will compensate for where we are in relation to where our sensor bar is, so maybe all that won't be necessary!
