It looks like there is a new CD offered to subscribers of U2.com, a 2CD set from the ZooTV tour in Sydney. I'm assuming it's the same show as was released on the DVD. The packaging of it looks pretty cool and it comes with a poster, I believe.
Personally, I've never seen the point in paying $40 to use someone's website. There doesn't really seem to be a lot of benefits for it, at least to me, anyway.
