Today, a leaked release list from Bethesda revealed the existence of The Elder Scrolls IV: Oblivion for the PlayStation 3 and PSP. The currently Xbox 360-exclusive RPG is reportedly slated for a port and a portable version, both due on November 6, 2006 (just a few days shy of the PS3 launch date).
No details on either version are available now, but it leaves the question of whether or not either of the ports will have microtransactions.
Check back for more information, hopefully in the near future.
