I am in two minds about this:
1. I like the idea of the XMB changing. The current one is kinda dull (except for sorting trophies - gee man what a way to alter something yourself on the XMB - only for those who updated though .... )
2. One should probably not stare all day at the XMB screen - the PS3 was created for gaming or OtherOS (not if you updated or bought a slim), and it is really a lot cooler doing that than staring at the XMB wondering "What should change?". I have no idea what the clever guys with the thick glasses and white coats at $ony are thinking ... Are they short of people thinking up clever ideas? For heavens sake - changing an XMB instead of all 101 things people REALLY wanted to see in the PS3 ... (and don't forget - you CAN sort your trophies ... if you upgraded)
PS: Sigh ....
