Lego has this website where fan-made models can become real, official Lego sets, and make it to production, which is awesome. One of these projects is a badass-looking Space Marine theme:
They need enough people to say they like the idea by clicking on a big green button. At that point, it will go to review, and if it passes, we'll have some Lego Space Marines on our shelves soon enough! So far, there are about 9,800 supporters, and the project needs 10,000 to go to the review phase. To make the winter review phase, it needs to hit 10,000 by December 3, I think.
If you get a minute, please visit http://lego.cuusoo.com/ideas/view/5127 and show your support for Lego Space Marines!
I'm just a fan; I have nothing to do with the Lego Space Marines project myself other than digging it. Yes, there is an official Lego space marine minifigure so far, but he's only available in a series of blind-bagged of minifigs, so it's hard to find him, much less army build them! And the upcoming Galaxy Force line looks disappointing, with garish colours and motocross helmets instead of the bulky space armour these guys have.
So please, visit http://lego.cuusoo.com/ideas/view/5127 and support the project. Thanks a lot!
