I don't know if anyone has posted this in another thread, but I just found out that they are recording/selling a CD of the Oblivion Ball - Makuhari show. You can order the CD at HMV Japan:

(It might automatically default to Japanese, but there is a link down on the bottom left that you can use to switch to English.)
They will ship to locations outside of Japan.
More live CD's - very nice!
