I've seen it in person at several stores now. This is a very new model. The local Goodguys has only had their display model for about 2.5 weeks, and my local Best Buy just got one in last Sunday.
So far, there's very little not to like in this model. The picture is very sharp and bright. I am seriously considering picking one of these up this weekend but am currently debating between this one and the Mitsubishi 42311. Also, I'm having some difficulty finding a good, inexpensive stand for this unit - at 143lb, 42" wide and 24" deep, it barely fits on Ikea's largest and sturdiest TV stand (the 'Magiker' series). I don't want to buy the stock Sony stand because it's too expensive and I'd like a stand that can fit more components (for me, 6 stacked components in 2 rows of 3).
