Lego is about to release Main Square (60271) in its City Theme line up. I think this is a great looking set, and something that I am considering for my collection.
The yellow train is definitely the favourite feature of mine.
Overall this set seems to offer quite a bit of things to build. I can definitely see how kids in the age 6-9 range would enjoy this set as there seems to be quite a bit of mini figures to go with it as well.
