Hiya!
Short answer? Nope.
Long answer? Probably nope.
They have stated many times that they are not going to go down the "splat book a month" route that 3.x/PF/4e did/does. IIRC, they basically said "we don't want to pump out rules upon rules upon rules...we want the individual DM's and Players to use the core rules to create their own stuff...we want them to make the game their own...make rulings that make sense for them and their game". They have (mostly) been sticking to this.
They have also stated they want a MUCH reduced product release speed; as I said, no more "splat book a week/month" craziness that basically destroyed 3.x and 4e (again, IMO).
The mantra of 5e is: "Rulings...not rules".
