I very much doubt this would pass. The internet is a booming industry in itself. It is a means of communicating globally and also making a living. By letting this pass, the millions of people who make their living on the internet (bloggers, people who sell things on e-Bay for a living, musicians who sell their own stuff on the internet) and big businesses who use the internet (being a globally accessible thing) will lose billions in advertising due to lack of traffic on key websites such as YouTube and Facebook. If SOPA was passed, entrepreneurs and bloggers, etc. will be unemployed all over the world and the economy will be affected severely (I suspect very severe considering the World Bank's previous announcement of an upcoming 'recession').
So no, I don't believe some bible-bashing, close-minded fools plan to destroy piracy will be passed. It has GLOBAL and ECONOMICAL ramifications.
And, to add, the guy behind TVShack was also arrested. But this was months before.
