Hollywood may need to start doing more with less in the future. Putting all their eggs in very few baskets of the "traditional" Summer blockbuster is going to prove a more and more risky proposition until all we get year to year are endless Transformers sequels, cut and pasted from previous scripts. Sooner or later, someone will stumble onto the obvious idea of diversifying their portfolio, figuring out how to make better movies for less money or just making a wider variety of movies.
I think, in general, the days of the behemoth movie companies are numbered. When they collapse, there will be a lot of creative people with nothing to do, but a love of movies and visual entertainment. Those people will probably start making lots of smaller movies on shoestring budgets and putting them online.

PS - For some people, that's probably all they can do, and so they did.
PPS - And I'm glad for it.
