All we know at this point and time is that the broadcast teams will become exclusive to each brand and we might be seeing the return of a two man announce team. In my opinion, this is something that has been extremely missed, because a three man booth on both brands is just too much to handle sometimes. According to reports we could be seeing Michael Cole finally move back to the blue brand after being the voice of Raw since 2008; which will be a welcome sight and extremely fitting knowing the huge step Smackdown will be taking in October. The only other report around at this time is Vic Joseph will be making the massive jump from 205 Live to Monday Night Raw.
Overall this is exactly what Raw needs as Vic will bring a brand new voice and identity to the red brand following the draft in October. I think Corey should move to Smackdown with Michael Cole exclusively keeping a solid team together giving Smackdown a two man booth. As far as Raw is concerned Vic Joseph should be partnered with Tom Phillips and Nigel McGuinness. Nigel should join Vic on Raw to help him ease into a new role with a partner that he had worked with prior and Phillips can be the experienced voice to help keep the pressure off Vic Joseph while he gets a handle on being on Raw rather than 205 Live. I know that keep Raw with a three man team might seem like we are missing the chance to downsize giving Raw three man team would allow Smackdown and Raw to have a different identity and sound.
Note: I didn't forget about Renee Young or Byron Saxton as I believe these two will join the upcoming FS1 recap show that Triple H mentioned a few months back. Clearly, Renee has always been a step above the rest of her workers due to her previous experience and how well she did on Talking Smack and shows along those lines. The reason I chose Byron to be Renee's second is, because I think Byron deserves a chance to show what he can do without Vince McMahon in his ear and if he make it work on different type of show or if he needs the safety that comes on Raw and Smackdown.
