Katamari Forever comes out next week in Japan and as a last minute news bit Namco Bandai announced it supports Home Rewards. In addition to collecting trophies, you can unlock the Prince and his cousins as Home Rewards items.
Katamari Forever is almost done. Namco Bandai will release the first Katamari game for the PlayStation 3 in Japan only July 23. The release date comes with a few tidbits, like the 100+ cousin count.
Katamari Tribute will come out in North America this fall under the name Katamari Forever. The "tribute" part in the Japanese title is appropriate since Katamari Forever takes levels from the previous games and remixes them.
