I don't trust MS PR (see FSX DX10 shots), my interest in a "social" version of FSX is pretty much non-existent, it overall looks like a cheap FSX spin-off and the trees are quite poor. Apart from that though it's definitely beautiful; not perfect for sure but still looking good.
Maybe add some lime green to spice it up a bit
(btw I can't watch the December pics anymore, no matter where I click - bug in Silverlight?
)
