There have been a number of potential replacements for jpeg, most notable flop was the jpeg2000.
Back in the early 1990's, there was a good reason to change from Gif to Jpeg, and that was due to very limited internet bandwidth that most of us had. so we accepted poorer quality for usefulness.
While photographers like myself would like to see a better image format, its a really hard sell for the average person. In 1992, there were few digital cameras, but now, there are trillions of jpeg files, and 99%+ are happy with what they have. That means that there would be 3 or 4 major formats, raw, jpeg, DNG, and BPG. If they started making cameras that had a option to save to BPG, few would use it, just hard core photographers, and they would have to convert to jpg for the next 5-10 years just to share files.
I really wonder if there is enough demand to go thru the pain of converting cameras, scanners, software, internet browsers, and a lot of other stuff to BPG over the next several years. There is also the thorny subject of silent patents which will suddenly appear after it gets adapted by a significant number of users, and require all software and hardware makers to pay royalties. Those companies will see BPG as a big risk.
I concur with your JPEG2000 flop comment.
I'm not so sure about the issues transitioning to the file format, however. Many photogs appear to prefer the DNG format (I've never used it personally), but how many cameras support that internally? Those who want to use it convert their RAW files during post.
For RAW shooters, it would be easy enough to convert to a new format, just as soon as the photo editing application developers added it to their Save / Save As dropdown lists. (Or conversion could be accomplished by means of a third party app.) And if it became popular, the various photo viewer apps / applets could add it to their lists of supported formats quickly enough.
I save a lot of stuff in TIFF/ZIP format, and routinely convert some of those to JPG or BMP, if needed for another application or wider distribution. Once I've used the JPG/BMP, I toss it, but save the TIFF/ZIP file.
