I'm hoping that we'll see more of a shift towards individuals writing about more niche subjects. For example, those learning biology will learn from smaller books, or, more likely, ebooks that cover specific things, like "photosynthesis." These smaller books, in theory, would be written by better writers focusing on very specific things, which means each section or thing students learn about is a better experience, and written by people passionate about a smaller subject. These will be cheaper, though the big downside is organizing all these smaller texts into a "class," though I think the experience with the books would overall be better.

Big textbooks are just so... drab and generalized. The self-publishing revolution is coming, and I'm hoping a lot of passionate experts take advantage of it and write smaller textbooks that teachers can use and students can buy (for a lot less).
