Visceral, DICE, and EA have just revealed that Battlefield Hardline has been pushed into an early 2015 launch. The first question that should pop into your mind is "why?" Here is why.
This feedback also spurred us to start thinking about other possibilities and ways we could push Hardline innovation further and make the game even better. The more we thought about these ideas, the more we knew we had to get them into the game you will all be playing. However, there was only one problem. We would need more time. Time that we didn’t have if we decided to move forward with launching in just a couple of months.

We decided that the right thing to do was to take more time to ensure Hardline is the best, most innovative Battlefield experience we can give to you, our fans.

Here are a few of the things the new timing will allow us to accomplish:
1. Multiplayer Innovation: Coming out of our E3 beta, internal focus tests, and work with our community, we have received a lot of great Multiplayer thinking. We’re going to be adding some new feature ideas direct from the community that will evolve the cops and criminals fantasy into a truly unique Battlefield Multiplayer experience.

2. Single Player Story Depth: In order to ensure our Single Player experience delivers on player expectations, we’re spending more time polishing our core features, as well as adding a few new ones that will support a deeper “crime revenge” story experience.

3. Stability: This has been a focus for our team since day one and we’re going to be using the extra time to continue to optimize the game for a stable launch. We have learned a lot from Battlefield 4, are continuing to learn from our Community Test Environment and will learn more from another Hardline beta. More time allows us to surface issues that the team can attempt to fix prior to launch.

I have to hand it to them since they're taking the necessary steps that Battlefield 4 should have taken to avoid a really rocky launch. Let's just hope the extra development time doesn't go to waste.
