I think it would look ok, we have a TV in the same position in the living room although its only a 47" I believe, but it looks ok so I doubt 55" will look out of place, and our 47" TV has a thick bezel. Most new TVs have ultra slim bezels.
*Nice PS3, always loved the original design on that.
I miss my phat PS3. Piano black finish. The 40GB model YLOD in 2012.
