According to various sites on the interweb this morning, Gran Turismo on PSP will not debut in Japan at the end of this year as previously expected.
Now, the date has been moved to early 2006, meaning we Europeans are likely to get it around summer or Autumn time. Of course, this is speculation.. All Sony has offered is a simple "We don't have a release date for this but i can confirm it won't be this year."
Ah well. More when we have it.
