I am hopeful about what happens N years after the patentocalypse, when everything has been broadly patented a million times over and then all of those patents expire, and it is no longer to patent anything again.
1. Prior art doesn't stop the patent office from issuing patents, so that's not going to help.
2. Patentocalypse is a great way to kill off startups that actually succeed and open source projects, so big business campaign contributors will keep congresscritters from doing anything about it.
3. This won't really hurt the big public corporations too much, once the dust settles a little, because they'll just reach detente to avoid mutually assured destruction.
If something changes things for the better, it will almost certainly be the general public ultimately reaching a point where everyone ignores patent law altogether, thus making it irrelevant.
