Some line-count trivia:

Nebula3 Foundation Layer
66,502 lines
Nebula3 Render Layer
73,465 lines
Nebula3 Application Layer
22,706 lines
Nebula3 Addons
32,847 lines
Nebula3 All
195,520 lines
Nebula2
239,279 lines
Mangalore
181,592 lines
N2 + Mangalore
420,871 lines

The N3 line-count includes the current code for 3 platforms (Win32, Xbox360 and Wii), the N2+Mangalore count only includes one platform (Win32). Looks like N3 will end up a lot leaner then the old code which is a good thing :)
