As it stands much of "epub 3.1" dc metadata will actually be closer to what epub2 dc metadata was. The big change will be in non-dc metadata where epub 3.1 would require no old fashioned (self closing) epub2 meta statements. The key things done in the old meta data can easily be done in the new style meta (and without refines) but things like cover image setting will be replaced by manifest properties.

Basically, the reason that readers that understand EPUB3 render better is not because of the EPUB3 part...it's because the HTML/CSS renderer has been upgraded along with the EPUB unpacker. There are many EPUB2-only readers that handle a lot more HTML/CSS than is actually legal in the EPUB2 specification. In the same way, a reader that understands EPUB3 will likely handle more HTML/CSS than is required by the EPUB3 spec, simply because the HTML/CSS renderer is newer. |

In all honesty, I would be more shocked if a reading system that supports EPUB3 didn't use an entirely different rendering engine than it does for its EPUB2 content. |

After the determination of whether a file is EPUB2 or EPUB3, the metadata read gets done, and the structure of the book sorted out by the program. At that point, it should then pass the first HTML page to the HTML/CSS renderer, and having different ones is merely code bloat. There is nothing in the HTML of an EPUB2 that will render incorrectly using an HTML/CSS renderer that is EPUB3-compliant. Quote:

It does not seem to me that there is any claim in that or subsequently that epub3 should not be used when it delivers benefits for cases when the media profits from its use or when the producer of the media otherwise desires for whatever reason whether useful or not. So, your response tells me nothing. Thanks for trying though. |

Let me step sideways or perhaps go off topic.
If I continue to produce ePub2 ebooks for the MR library will they be readable in ePub3 readers? Are there any ePub3 only readers? If I want to learn how to produce ePub3 ebooks where can I go to learn how to do it? |

Some epub apps, e.g. ADE 4.5/RMSDK 11.5 will actually use different rendering engines for epub2 and epub3 books. Quote:

What surprises me is how developers stagnate their software. For example, Kobo is not using the latest RMSDK.

I'm not pushing Sigil or anything, but after you know how--and can--build an epub from scratch, the knowledge gained is the only advantage--and that knowledge is invaluable. But it doesn't go away just because you start using an editor designed specifically for epubs.
There's no style points given for manually handling each and every tedious change to the opf/ncx/nav file required by changes to the other files. There's no style points for manually changing the url/anchor in every link throughput your xhtml files just because you've decided to rename an file. Using an editor like Sigil (or calibre) also means it's impossible to forget to add the mimetype file to a zip archive. It means you don't need to worry about making sure the mimetype's the first member of the archive and is uncompressed. It means you don't have to worry about creating/maintaining zip archives at all. Letting software manage the opf and the zip structure frees you from the mundane portions of epub building. It allows you to focus almost entirely on the xhtml/css. It allows you to work more efficiently. And using Sigil doesn't mean you have to give up CoffeeCup as your XHTML editor. Sigil has allowed epub creators to use external editors for quite some time now. But you're right, there's no urgency to change. Especially if you actually enjoy working harder/longer than you need to. (That's not a personal dig. I realize there's many who adhere to a "if it ain't rough, it ain't right" type of philosophy.)
