was not enough, it has also been confirmed that EA's Rock Band is on its way to the machine, too.
Dubbed Rock Band Unplugged, it's the first portable version of the popular musical instrument title to be announced. And like its home console cousins, the game will also support a dedicated content store accessible via the PSPs wi-fi capabilities.
Whether it will rely on peripherals or add-ons is not yet known.
Other EA titles confirmed for Sony's handheld this year include Madden NFL 10, which will boast PS3 connectivity, and Tiger Woods PGA Tour 10.
Sony has also confirmed a Western release for best selling Japanese PSP title Dissidia Final Fantasy from Square Enix.
