Jonah Lomu Rugby Challenge has been given a provisional release window on PS3 and Xbox 360, but no specific date can be offered due to "a few unforeseen issues."
The Rugby World Cup is currently underway in New Zealand, which of course is the perfect time for any sporting game to release. However, the game won't be coming out until at least the 23rd of September. But at the latest, it'll be out by the 21st of October.
The publisher also mentioned that the PlayStation Vita version of the title is still in development, but that will be coming at a later date as a separate entity.
