Namco-Bandai recently spilled the beans on a sequel to the insanely-awesome Ridge Racer
for the PSP. Currently at 70% complete, the sequel is to release to the Japanese gaming public on the 14th of September, with no current announcement on US release, which is bound to happen. This announcement, which made its way to us via Japanese gaming mag Famitsu, sees the sequel following in the footsteps of the first title, complete with the existing nitro system and drift-focused racing.
[Update: Wow, two typos in two titles in two posts in a row. I swear I'm not on drugs.
