PlayStation Vita claimed a rare first place in the software sales chart this week as Hatsune Miku Project Diva F beat a flood of newcomer releases with over 150,000 unit first week sales.

Impressive figures, no doubt, but possibly not impressive enough for a sequel. After Enterbrain and Media Create released their sales stats earlier today, Miku series spokesperson Nakanohito said at Twitter that based off the current sales tend, making a Hatsune Miku Project Diva F2 would be difficult. The reason is that F's development costs were so high.

Nakanohito says that the download version of F sold about 10% of the package version. He believes this is a typical figure for games.

In a later Tweet, Nakanohito explained that the current sales make the team at Sega want to work hard to get more people to buy the game. Their goal is to make it the number one selling Vita game in 2012.
