In December 2008, Pioneer Corporation unveiled a 400 GB Blu-ray Disc, which contains 16 data layers, 25 GB each, and will be compatible with current players after a firmware update. A planned launch is in the 2009-2010 time frame for ROM and 2010-2013 for rewritable discs. Ongoing development is under way to create a 1 TB Blu-ray Disc as soon as 2013.
