An announcement trailer was said about the Kingdom Hearts game series, re-releasing 6 of their games, apparently together? The info is as follows,

Kingdom Hearts HD 1.5 + 2.5 ReMIX announced for PlayStation 4, celebrates 15 magical years of #KingdomHearts with six memorable adventures, including:

• KINGDOM HEARTS FINAL MIX
• KINGDOM HEARTS Re:Chain of Memories
• KINGDOM HEARTS 358/2 Days (HD remastered cinematics)
• KINGDOM HEARTS II FINAL MIX
• KINGDOM HEARTS Birth by Sleep FINAL MIX
• KINGDOM HEARTS Re:coded

Coming to PlayStation 4 on March 28, 2017 in North America, 31 March 2017 in Europe.

So does this mean, that ALL OF THESE GAMES will be released TOGETHER as 1 game, or in a box set or what?

How can they fit all 6 games on 1 single disc though, isn't that a LOT of storage space, needed for a few discs?
