It seems to me that the best way for WotC to "sell more stuff" is to offer setting options for players and DMs in popular fictional universes, for example Harry Potter (who wouldn't buy the DMs Guide (and Players Handbook) to the World of Harry Potter), or heck tie in with Avatar (there's a bunch of probably mediocre movies coming out for that...) And of course many video game worlds. In fact there are 3 books to sell: Players Guide, DMs Guide (setting details + monsters), and introductory Level 1-10 adventures. 3 ~ 256 page books (maybe the players is only 128 - but really you could make it 256 with a bunch of nice art/pictures
)
Now this will mean cutting the pie a couple more ways (for the licensing) - but Hasbro knows that business inside out.
In fact this is the way a movie tie-in should go IMHO: Loved <insert popular movie here>? Continue the fun with the official D&D compatible RPG "Adventures in <movie world>". Rather than WotC making their own mediocre movie, ride the pop culture coattails of someone else's!
First off, I wouldn't buy a HP D&D book because I'm not a fan of HP. But your point is taken: most people are, and given that I would love, say, an Earthsea D&D book, I get what you are saying.
Keep in mind that superhero movies used to be terrible too. All the way up to 2008. But they kept trying anyway and eventually they did it.
We now have a model for that sort of movie that works. I don't see why D&D can't just copy it.
Gonna have to disagree with this, as it is a very "MCU-centric" view. There have been plenty of good superhero movies well before 2008. While they're rather dated, the first couple Christopher Reeves Superman movies were quite good; the Keaton Batman movies (also dated) were very good. The first couple X-Men (especially X2) and first couple Tobey Maguire movies were all good.
But yeah, the MCU formula is a good one (although to be honest, I'm starting to grow a little tired of it and really enjoyed a re-watching of Batman v. Superman and its darker, more epic tone - not so much Justice League, which tried to "do an MCU").
I’m arguing that instead of a new edition, they will just stop print sales and make changes to an “evergreen” 5e via updates to the digital.
Again, as paper costs skyrocket over the next few years, it may no longer be economically viable to print 200+ page hardcovers, thus forcing WotC’s hand.
Part of the reason D&D books rank so high in Amazon sales is because most books are bought digitally now.
Or because $30 for a 300-page high quality hardcover that can be used for years and years is a fantastic deal, and Amazon sells in such quantity that they can make a killing with fractional mark-ups. So let's say your FLGS sells a PHB for $50 that they spent $30 on and makes $20; Amazon sells it for $30, and spent $25 on, so only makes $5, but $5 x 300,000 = $1.5 million.
Anyhow, you may be right that the digital version will become
the core rule book. I haven't downloaded it yet, but didn't the new version of the Basic Rules have a jump in quality with some nice art-work? Maybe they're already laying the ground for this.
That said, people will always want print versions of the rules - at least as long as Gen Xers and Boomers are playing, which are some decades yet. Maybe Millenials--and more so, the younger "Gen Z"--as a group are OK with digital only, but I know Gen Xers aren't (again, as a group). Perhaps a hardcover will become more of a novelty product, and prices will go up so there will be fewer around, but hardcore fans will still have them.
