Harmonix Hoping to Release Amplitude on PlayStation 3 in Early April
In an update on their Kickstarter page, Harmonix has announced they have submitted Amplitude on PlayStation 3 to Sony for certification. Once that process completes they hope to release the game in early April, though are not making promises just yet.
Vinyl discs are in production and will probably ship after the game does, with a mid-to-late April window. The art book has been completed and is already being distributed to eligible backers.
