Does BPG support burst mode photos? If so does it use I/P/B frames for the other frames? This is an important consideration. Another consideration is if it can store audio - essentially every photo on iPhone is a short video with audio. Hopefully the HEVC patent holders are reasonable and license under liberal terms - the market and opportunity is much much larger than just videos and HEIF has decent chance of killing jpeg.
