Another Architecture set on the way
Several eagle-eyed Brickset visitors emailed to say that the Architecture site at LEGO.com has been updated with a teaser image of set 21009 which is being launched in April. Does the small section that's not under wraps give any clues as to what it is? Take a look and see if you can guess. (thanks sdpevrin, attisb and zaxter)
Update: member Shadow Crawler has identified it as being the Farnsworth House which you can read a bit about here. I reckon he could be right!
