An inside connection I know has told me TBBR has not yet been greenlighted... Pre-production stuff is happening, but whether it goes into production or not will likely depend on how well TLM2 does. TLBM and TLNM did not do as well as expected, but hopes are high for TLM2. Plus the original deal was for a total of four movies, so...  with TLM2 being #4, we shall see. Good box office will lead to more movies whether they (WB) sign off for them one at a time or sign for multiples.
