Some more evidence that Sony plans to offer digital rentals of PSP games has popped up.
Over on The Retail Gamer, there's an option to sort DLC games by expiration date, and there are list options for "starts" and "hours left".
This is already done with movie rental content.
Rumors of the game rental service started in May, due to Sony sending out a consumer survey asking for opinions on such a service.
Of course, when contacted, Sony replied that it "don't comment on rumor or speculation."
