The playtest material is online, but it will be published in book form when it is officially released.
Well of course not. Unless you're part of the playtesting, you wouldn't.
Online resources are wonderful.
Here's a link to a 6th level Circle of Dreams Druid I play.
D&D Beyond Character Sheet
The World's most intelligent Dungeons and Dragons Character Sheet.ddb.ac
Want to check details on a spell? You can grab the PHB and flipping pages, only to find out that this spell is from one of the supplements, you can just click on the spell. Boom.
Character info? It's there, but you still change it yourself. The big difference is you won't wear out your Current HP by repeatedly erasing the field.
I prefer to roll my own dice. Because I just do. And so I generally do. But it's also nice to know that I could, if I wanted, join a game using nothing other than my iPhone.
And there's nothing better for beginners. Making a new character but some of the details are unfamiliar to you? No worries. The system will not allow you to break the rules.
[Edit to add]
The character I linked is a good example. Not sure how the Circle of Life healing bonus interacts with the Druids Goodberry spell? The system knows, and you will learn.
Don't have all the sourcebooks? Also no problem. D&DBeyond, at least, allows a player to share their online sourcebooks with everybody in their group. I have all the online resources (and most of them in paper as well). I created a campaign called "Marks Materials Management". I can send that link to people, they join, and they have access to all of those sourcebooks, same as if I handed them the book across the table.
Not to worry. The availability of online sources will not affect paper publishing.
I use the online and PDF versions far more than the paper, but there's nothing stopping you from using a pencil. Or a quill and ink bottle, if that's how you roll.
Good info, thanks. And yeah, there are so many supplements now, it seems you never have it all. I can see that as an issue.
I just like books.
Before 5th was rolled out they play tested "Next" at Gen Con and Origins and other places.
It was also rolled out online for some basic information .
They have kept their online material for play testing - Unearthed Arcana - is the area they use for this material.
I would like to play, only Work and other games would not allow for the time. So please enjoy and keep us posted.
