A placeholder release date on PSN for Resident Evil Revelations 2 is being widely reported as confirmed, so an update on Capcom Unity explains the episodic survival/horror sequel does not yet have an official release date on any platform, though they do say it will launch early next year:

Hey guys, this is just a public service announcement that the release date you're seeing listed for Resident Evil Revelations 2 - Complete Season on the PSN Store is merely a placeholder date (these are required for digital pre-orders); the true release dates for each chapter as well as the retail version are all still pending. Don't be fooled!

Resident Evil Revelations 2 will launch via weekly episodes in early 2015. The Complete Season pack, available for pre-order as of today, will allow purchasers access to each chapter as they are released, as well as the RAID Mode "Throwback Stage Pack" and some further bonus content currently undisclosed.
