Well, a lot of news came out from Starbreeze Studios today. In honor of it's 100th update, the company announced that it had acquired the full right to the Payday IP from Publisher 505 games for 10.9 million B-shares. The release also says that "505 Games will retain a 33% revenue share of Starbreeze's net revenues from future sales of Payday 3 capped at 40 million USD, after Starbreeze has fully recouped its development and marketing costs."
In the announcement, Starbreeze mentioned that Payday 3 will be released sometime in the future. Destructoid was able to confirm with Overkill Softwares' Almir Listo, with Listo saying, "we're confirming it's existence, but that's it - no more." He did say that the studio will "continue to develop stuff for Payday 2 for another 18 months" on Overkill's Steam page.
Also confirmed on that post is that the black market will be free for everyone going forward. Essentially, the much controversial microtransactions that were implemented last year will be no more.
Payday 2 was released on August 13th, 2013, for Xbox 360, PS3, and PC. A next gen port for PS4 and Xbox One scheduled for June 16th, 2015.
