Sony Bravia KDL-55X4500 55in LCD TV Review

The 'floating' speakers effect look much better in reality [i.e. setup at home] than pictures give it justice [based on my 40Z4500 which has a similar single speaker bar, but underneath the picture]. Though the speakers being on the side here might make this look too wide and suggest unstability?
A drawback of the 'Z' is that carrying TV is awkward as manual says not to lift TV by holding under the speaker which is the easiest/obvious way.

Not quite sure of the Sony model letter scheme [55'X'4500] where progressing through the alphabet used to [roughly] mean a more premium model e.g. S->U->V->W->X->Z, which made it easy [for me] to remember i.e. the 'Z' should have been the new 'X' and this X4500 the 'Z' [what's wrong with 'Y'?].

I'm a bit upset about the 10/10 image quality rating. The only other TV on Trusted Reviews is the Pioneer Kuro range. Now, the Pioneer Kuro range does not have the image issues that this sony has.

What's going on?

Although the comment in the review is presumably true for UK-released screens, technically this is not "Sony's very first LCD TV to use LED backlighting". I have owned a Sony Qualia 005 since the end of 2004, which is an LCD tv that also features LED backlighting. I can't believe it's taken 4 years for it to be added to their Bravia lineup..

Would you prefer this TV to the Samsung 7000 or 8000 on picture quality?
Samsung has the better connetivity, especially with the blockbuster deal.

Does anyone know if Sony is updating it's connectivity offering?
