Looking forward the seeing how the new upscaling engine performs at my local Sony Centre after being seriously underwhelmed with the chipset from last years range.
Also it's disappointing that in a three page review you devote just a single paragraph to the subject of upscaling and instead focus on guff such as 3D and online stores. Over 90% of the content viewed by over 90% of the national population is SD and yet the performance of most television sets is akin to watching your neighbours TV through their window and net curtains.

It looks like the HX range of Sonys TVs that carry 3D the best.But the previous post is spot on.Only about 5% of time will be taken up with 3D viewing & there is too mush emphasis on 3D,so not nearly enough on standard 2D viewing along with HD2D.Some of these TVs are getting panned even though the review should be mostly how the TV performs for everyday,realworld viewing.Build quality on highrange TVs has little or no cover.When & if,big if,3D becomes the standard,then maybe concentrate on the 3D capability.If i thought i could get a 46" LED backlit TV for less than 1000,id have taken it gladly,Regardless of 3D!
