Halo 4 New Forge Information (Post Here)?

I have been looking a lot online at information regarding Halo 4’s forge system. It seems the forge system is exactly the same as Halo Reach’s. The only notable differences are the snapping, magnet, object clear selection , and player trait zones. What I am looking for is any information regarding the budget limitations, the object number limitations, the total number of objects allowed in a map , and thow the diffrent object groups work. From what I can tell so far the “forge system” IOW how it works is the same. I don’t understand why a 1x1 object costs the same as a 5x5 object unless they use the same number of polygons. Anyways if you can post any information released here It’d be great… THANKS!
