if you're referring to online magazine reviews, not sure if there are any up yet. On the other hand, in print, What HiFi has consistently given the Bravia V 40" 5 stars and called it "the best LCD we've ever seen". They reviewed the screen about 3 - 4 months ago, and then again in the April issue of the magazine.
Also, there's a VERY large thread on the V-series in this forum - for me, end-users' experience is worth far more than the opinion of a potentially biased magazine, especially when MANY end-users say the same thing (that they love the set).
Here's an excerpt: Displayed images were unusually sharp with rich and vibrant colors on the whole. The colosseum showdown between Maximus and Commodus in Gladiator came alive with deep red roses, true-to-live skin tones and good shadow details. We could even make out the perspiration on Russell Crowe's battered face during one of the many close-up shots in the highly charged clip.
