The entry-level 2013 TV range is the R4. This looks much like the W6, with the same stand design, and will come in 32, 42 and 46in screen sizes. Unsurprisingly, it doesn't have X-Reality PRO, but retains MotionFlow - an intelligent frame creation algorithm which smooths motion in lower framerate material, and is good for watching sports.
It will also have MHL support so you can hook up a compatible smartphone to mirror its screen via HDMI.
Triluminos demo comparison
The Triluminos filter on the X( and W9 ranges ensures that more red and green light is able to pass through the LCD panel, providing not only better reds and greens, but also enabling a more natural look and greater differentiation between shades of colours. In particular it makes it possible to see more clearly the difference between reds, oranges and purples. The image below demonstrates this in action. The top TV is a 55in W9 set, and the bottom TV is a 55in Samsung ES8000.
We haven't edited the image except to crop it, and it clearly shows how the Triluminous filter allows the Sony set to display subtly different shades of red and orange. The Samsung - itself an excellent TV (see our review of the UE46ES8000) - simply cannot reproduce the shades and they merge into one, so you can't read the text.
