Hardline is a separate game made by another EA studio- it has nothing to do with Dice, aside from using the frostbite engine.
Their is a news item on battlelog where Dice says that their are 3 teams still working on BF4 and they clearly state Hardline is separate from BF4, the next BF title will be BF5.
The industry is driven on profit, its up to the publishers to say when a game will be out, developers only get so much time and funding.
What you need is for publishers and backers to allow studios enough time to ensure the games are polished and ready for release.
