PSP has been following in the footsteps of its PS3 big brother for quite some time now. The latest trend it's starting to pick up? DLC. Owners of the PS3 have become accustomed to purchasing post-release content through the PlayStation Store, and it appears PSP owners may follow suit.

Prinny: Can I Really Be the Hero? will feature a brand new downloadable level featuring cameos from another Nippon Ichi game, Phantom Brave. "Phantom Isle & Marona" is downloadable on the Japanese PlayStation Store for 300 yen ($3.30). See the video after the break.

Although Prinny hasn't released in the US yet (it's coming out February 17th), we're certain NIS America will follow suit and charge for these extras. It'll be interesting to see how PSP owners respond -- will they be as eager to pay for DLC as PS3 owners?
