Preorders for Battlefield Hardline are already being offered Amazon.com and Origin as either a $59.99 standard edition or a $69.99 deluxe edition, with Origin showing a fall 2014 release and Amazon listing a December 31, 2014 release date for the just-announced shooter sequel (thanks MP1st). Just because they are selling the deluxe edition, however, doesn't mean they are ready to reveal what you get for your extra ten dollars, as they say: "Check back on June 9 at 1pm PDT for more information and videos from Battlefield Hardline, including a more detailed description of the bonus content included in the Digital Deluxe edition." There is also an update on The Battlefield Blog where DICE's Karl Magnus Troedsson promises continued support for Battlefield 4 in light of development of the new game:

Let me tell you about a few ways we’re going to continue to improve the BF4 experience.

Continued Support: There are dedicated BF4 teams in Stockholm, Uppsala and LA that will continue to address any issues that might occur. But more importantly will also look to make significant additions to the game.

Netcode Patch: We are also working on a major update to the Battlefield 4 netcode.

Community Test Environment: We launched and are planning to expand our Community Test Environment. You can see the CTE as our labs environment in which we’ll continue testing out new additions, improvements etc. before we go live with them. We’re expanding the CTE program to give more and more players the chance to test new additions.

More Features: Other features rolled out recently such as Squad Join, Rent-A-Server and Loadout Presets, many which have been directly requested by you in the community. This trend will continue.

The games we develop are services. We focus on taking care of the games post launch, delivering new content to those of you who want it and always working hard to increase quality of play. We also continue to work hard to keep investing in areas where you tell us you see opportunities for improvements and new features. Yes, we’re very excited to partner with Visceral on the development of Battlefield Hardline, but ongoing work to refine and enhance BF4 remains a top priority.
