LEGO is releasing the Millennium Falcon model from Star Wars, and billed it as the largest LEGO set ever made (33" long, 22" wide, and 8" tall, with over 5,000 pieces, built to minifig scale, so Han Solo & co. minifigs can sit inside the cockpit.)
You can pre-order one for a half a grand: http://shop.lego.com/ByTheme/Product.aspx?p=10179&cn=240 - Thanks Atila!
I am a huge Lego fan, and I'm super-jealous of the guys who can order this. I tried, but my wife put her foot down. So I created http://www.BuyMeALego.com to trade links/ads for tiny donations. If you know a small business or blog that needs more traffic, send them my way!
A problem I've noticed is that almost all of the LEGO sets in my local retail stores are chock full of very specialized pieces so that the kid(s) can build 1 specific model. In the old days, the pieces were a lot more generic (and cheaper) and children were able to use their imagination and creativity a lot better. Sure, what they wound up with looked a bit less like the Millennium Falcon, but they figured it out on their own, and when they were done, they could take it all apart and turn it into 1000 other models. Good luck finding the old "buckets of bricks" they used to sell. Yes, I know they are still offered that way, but I need to mail order them b/c the local stores only sell "Harry Potter", "Pirates of the Caribbean", or "Star Wars" sets that are highly constraining (and expensive!)
