Earlier today, SilentTigeR let us know HERE that PlayStation Home Xi: The Hub is now available for PS3 users.
Now, PlayStation Home Community Manager CydoniaX has officially explained what Xi is on the PS Blog (linked above) as well as on the official PS Boards as follows:
The world's first console-based Alternate Reality Game starts today in PlayStation Home.
Called Xi , the adventure takes place in a series of secret areas in Home - and beyond - changing day by day, week by week, in real time. Anyone with a PLAYSTATION 3 can join in the fun for free.
To discover the mystery of Xi, simply log on to PlayStation Home and look for the graffiti on the wall in the main square.
Find that, and all will be revealed...
