Pro Tip: Send your PSP to Sony for repair, or buy a new one. I got mine used for just 60€.
Anyways, PREORDERRR BOOONUUUUS

Buy Hatsune Miku Project DIVA extend, and Sega will give you a "VOCALOID extend REMIXIES"
[sic] CD as a bonus goodie. [...] The soundtrack consists of seven remix tracks sung by Miku and her fellow Vocaloids. [...]
• Start of Rainbow ~first step~: Remix of the Project DIVA Title Theme by Dixie Flatline
• Day of indigo, ~ second flight ~ fly Sky: Remix of the Project DIVA 2nd Title Theme by baker
• Extend your wave ~ Prayer of Love: Remix of the Project DIVA Extend Title Theme by wowaka
• Live and Learn: From Sonic Adventure 2
• Ignite Infinity: From Phantasy Star Portable 2 Infinity
• Moshimo Kimi ga Negau no Nara: From Valkyria Chronicles 3
• Love 14: From Virtual On
Source (and also shameless plug)So if you pre-order now, you get that ♥♥♥♥, including a freaking version of Live and Learn sung by Vocaloids. YESSSSSS.
Also, if you don't like importing and don't give a ♥♥♥♥ about an actual UMD, PDe will hit the Japanese PSN Store on 15th. That means you can just buy it on there (guides on how to buy stuff from the Japanese PSN Store are on Google).
EDIT:
RELEASE DAY
UMDs EVERYWHERE
EVERYONE IS HAPPY...I'm waiting for my copy to get shipped... *F5 F5 F5 F5 F5*
