Do you think this will replace mp3
MP3 was a breakthrough for its time. If you were on a corporate network, or similar bandwidth level, you could stream music in realtime; on a dial-up connection you could have a song in about 20 minutes to play as many times as you liked; and, if you had an actual MP3 player you could cram a significant amount of music into a very small amount of storage space.
Then came the notified-by-stealth patents; thou shalt have a license to use a couple of mathematical formulae.
Everyone, today, that I introduce to OGG finds it - fidelity-wise - a far better format; the bandwidth woes are receding, if not already gone. Take your "shiney!" and shove it! I want something I can rely on to continue working for my grandchildren.
