If you like both Persona and music, congratulations! You’re probably a human being. Plus, it’s a pretty good day for you.
According to Destructoid, if you pre-order fighter spin-off Persona 4 Arena you’ll score a bonus soundtrack CD. Arena hits the US in August with no European release confirmed as yet, for PlayStation 3 and Xbox 360.
And over on Siliconera, check out details of some sweet bonus content in Persona 4 The Golden, including Persona Music Live concerts. Atlus expects all the content from the Japanese version to make the transition to western release, minus a few commercials which have licenses attached to them. The Golden is an HD re-release of Persona 4 for Vita, and arrives in the US in October, with, again, no European launch confirmed as yet.
I’d send you off to Atlus to gather more information, but the site is down for maintenance at time of writing.
