While a major "ver.B" upgrade to Sega's Hatsune Miku Project Diva has been seen dancing its way into test locations at Tokyo arcades in Akihabara, Ikebukuro, and Shinjuku this week, "ver. A" is still getting love with a revision 4 update, planned for June 14th.
Revision 4 added four new songs.
The first two songs being added are imports from the PSP game, Project Diva Extend :
☆結んで開いて羅刹と骸 (Musunde Hiraite Ratsetsu to Mukuro)
Music, Lyrics and Jacket picture designed by ハチ (Hachi)
☆番凩 (Tsugai Kogarashi)
Music, Lyrics and Jacket picture designed by 仕事してP (ShigotoshiteP)
The other two are first-timers.
☆Gothic and Loneliness ～I’m the very DIVA～
Music & Lyrics by なるしまたかし (Narushimatakashi)
Movie & Illustration by 桜羽りん (Rin Sakuraba)
Music by しばいぬ (Shiba Inu) / Lyrics by 綾取り (Ayatori)

In addition to cosmetic changes, advances in "ver. B" include:
A rival system for comparing performance to a friend on Diva.net
The ability to take screenshots in PV viewing mode and send them to your PC through Diva.net
Random song select mode
Excellent clear evaluation - requiring at least 80% accuracy for Easy, 85% for Normal, 90% for Hard, and 95% for Extreme.
It also has newly added Twitter integration.
