I've been at BrickMagic in Raleigh, NC this weekend. Yesterday around 1:50 PM, the Pet Shop was officially unveiled. My photography skills remain a bit poor, but I did get some photos of details that I haven't seen elsewhere, like the storm cellar. I can also confirm that the color of the Pet Shop is indeed sand blue.
I'll be able to take more photos today and on Sunday - let me know if there are any angles you'd like me to try to get. Word is that LEGO stores everywhere will be allowed to sell these on Tuesday (naturally, the day after our convention discounts expire). You can see my photos from BrickMagic (including the Pet Shop and several great town and train layouts) in my BrickMagic 2011 flickr set.
