TV: to hide or not to hide?

I am lost as to where we place the TV. We have a wood heater that we need to install between the lounge room windows. The only option for the TV is on the opposite wall, above the fireplace, next to the sliding doors or fixed to the wall in the far corner of the room on a swivel mount.
Open to suggestions for where to place this well used piece of technology. Our TV is a 42inch and we normally have a pay tv box and the wii/playstation hooked up.

This image shows the layout of the room, not including our 3.5 seater lounge (2.5m in length) and pair of arm chairs (0.7m wide each).

 

The lounge/dining area is 4880 X 9520, of which 4690 is allocated to the lounge area. 

This is what my instinct is saying, yet having my couch in front of such a large window is not quite ideal, as it's leather.

What about a TV above the fireplace? I am undecided and indecisive. This decision may drag on.
