The new file format will need to have the following features to be of use to serious photographers.
1) Must be able to save the image data in a 16 bit format.
2) Should have the ability to save HD image data in at least a 32 bit format. This might allow a camera to take two or more frames at different exposures and then combine them into a a single HDR file inside the camera.
3) Will need a lossless compression option.
4) Will need to have an option to retain the image data captured by the sensor without any in camera processing, sort of like a RAW or Adobe’s DNG file format, but packaged and compressed into the new file format.
5) It will need to support a color space wider that sRGB, such as AdobeRGB or ProPhotoRGB.

From what I have read, the new jpg XR file format will address most if not all of the items I listed above. Let’s hope that if this is truly a viable replacement for the existing jpg format, that it does not end up a dead end like jpeg2000.
