NeonCon has posted a lecture by Erik Mona titled "RPGs in the 21st Century." It's interesting, especially from the publisher-side view of things. He does spend some time slapping around the computer RPG strawman, but not as much as you'd think. He's far more interested in the possibilities of tech.
Paizo is probably among the best out there at building connections with their audience and making their customers feel like Paizo is their company. What I find interesting is how a similar dynamic is developing in the OSR. I feel invested in the success of folks like Mr. Raggi and Grubman. Mr. Mona's got quite a bit to say about that, including its use as a deterant to piracy and how important social media is to that mix.
What I expect to be really fascinating is the intersection of tech with the "old ways." For instance, it's a lot easier to include a CD in a boxed set than it is in a book. I don't think RPG publishers are ready to start including specialized handheld devices in their boxes, but software is certainly an option, as are collections of clip art, tile sets, and icons for use on message boards and gaming software like MapTool. I've also been contemplating the use of audio files; if the audience is, in fact, greying, that means most of a company's customers may now spend 30 minutes to an hour each weekday commuting. They can't read a gaming book during that time, but they could listen to one. Only, numbers and crunch don't work as well in an audio format, so you'd want to focus on style, setting, and flavor for your audio additions. If the boxed set revolution continues to gain traction, I'd be very surprised if some sort of digital additions didn't make their way into the box sooner or later.
UPDATE: Zak S. makes a strong (and completely different from mine) argument for raising the profile of audio media in our hobby.
