Despite what EA has said time after time, Battlefield Hardline will not be coming out on October 21st, but instead has been pushed back into a later date sometime during 2015. While it is still unclear as to what day, or even month of the year it will be released, one thing can be for certain; EA has been slacking a lot. In addition to Battlefield Hardline being delayed, Dragon Age: Inquisition has been pushed to November 21st.
It looks as if EA has bit off a little more than they can chew, but they have included a reason as to why it was delayed. EA claims it is "the right thing to do" and that it would "insure Hardline is the best, most innovative Battlefield experience we can give to you, our fans." It seems like either two things: EA is getting overwhelmed at the fast approaching release date and couldn't fit it all in, or that they're genuinely trying to make Hardline the best it can possibly be and trying to please the community.
Later in the blog they also included that during the Beta release, the Visceral Games team retrieved data and observed what players wanted to see included and are trying their best to include them in the game. Most things they're adding are just miscellaneous stuff, but there are three main additions they plan to add.
The first thing they plan to do is upping the multiplayer innovation. Troedsson points of that the longer time they now have due to the later release date will ensure that Hardline will "evolve the cops and criminals fantasy into a truly unique Battlefield Multiplayer experience." What this means is that when you're playing Hardline, there will truely be a feeling of newness and unfamiliarity, but at the same time it will still retain the classic Battlefield style of play.
Another factor they plan on making better is the single player story. Unlike many other games which don't spend as much time on the campaign as they should, Battlefield campaigns have always been one of the best because of the amount of work they put into it. Much like the older versions but with a huge upgrade, Hardline's single player story will "Polish" the core components of the single player, but will also include many smaller features that will all add up to a totally awesome single player.
The last and final factor is stability. In the blog, it states how multiplayer stability is their number-one concern. As with many other high-traffic games, one of the developer's main concerns are always whether their servers would be enough to support all of the fans trying to play. This means that they're trying to avoid people being denied access to their server due to an overload of activity, much like the problem GTA:O had faced.
