Why the hell WASN'T there a demo?

Anyway, about the ranking system. I was listening to the 1up Podcast from the week before last, and they were talking about it: The cap is at level 55, and you then have the option to gain a unique insignia next to your name and start all over, but this can only be done up to five times. Also when you start over, you give up everything you have earned, so the 1up guys were thinking that a lot of people probably won't bother unless they're goaded into doing so by other gamers who say they lack the skill to do it all over again blah blah blah. Anyway, if you cap at the fifth insignia, you then get all your weapons retextured to be made of gold. That's it.
I don't see many people bothering...it really is for the hardcore.
