Rejecting the ACTA treaty with such an overwhelming majority definitely pushed their plans of passing the TPP (ACTA's successor) treaty at least 2 years back. And it may even have put doubts in their minds about that their strategy so far and if it's still the best one to go.
I think the most important part is the idea that it is creating opponents elsewhere.
E.g. manufacturers that badly wanted the relatively non-controversial anti-counterfeiting measures in ACTA must now be furious at all the lost effort and the years wasted because of issues largely unrelated to their own concerns.
If more and more of these companies see RIAA and MPAA's lobbying as increasingly a threat to their own interests, it is going to have very interesting effects.
We should not forget that ACTA was not just terrible concerning Films and Music. It was botched on a much larger level. Like "protecting" poor people in third world countries from fake medicines... that could be harmful to them... but actually are just generic version of over-protected medicines sold for a fortune by richer countries, and works just fine at a much lower cost.
So even without the article 27, it should have been stricken down (with small exceptions like brand protection etc). Let's not have a fight just to save what concerns us most directly, but for a new conception of copyright, patents and the entire intellectual property landscape.
