MISIA and X JAPAN already released their old concerts in blu-ray box. (As expected, some old concerts have been upscaled which mean there're not real HD except the uncompressed sound)
MISIA's release is only 25000 yen for 11 discs. I think it's because of 15th anniversary thing so they sell it in special price. While X JAPAN's is 42000 yen for 6 discs. Common price, isn't it?
So, someday avex may release ayu's blu-ray box for sure...
