Sony PlayStation Network director Eric Lempel has announced that PSP firmware 5.01 is due out for release shortly. As indicated by the version increment, this will be a minor update, addressing an issue related to Memory Sticks PRO Duo cards over 8GB in size. The issue in question resulted in an out of space notification at times while downloading content from the PlayStation Store, even if enough space was available.
