Without going to into things, I could see them disbanding Sanity and sending Dain to NXT-UK as a main player, moving Eric Young to a producer role, and sending Wolfe to be repackaged in NXT. Dillinger I could see leaving. Plus with rumors that Brock will be in talks with AEW, UFC, and WWE we could lose him as well. Not to mention, coming soon to generic entrances: Shielded Lunatic and Cure for Insomnia.
2K20 will need a bigger legends roster and an expanded developmental game. If you're going to be signing all the UK scene to deals, then some of their talent needs to represented in game beyond Dunne and Bate. People like Regal and Albert should also still be in, either as their modern or retro personas. I say now more than ever they need to implement either a WWF vs WCW showcase spanning from Starrcade 83 to Survivor Series 2001, or something along those lines. The legends roster has been severely lacking in the past few years. The way they do DLC has been as well. They have to do a lot of work, especially if AEW picks off and gets a game deal as well.
We certainly live in interesting times for Pro Wrestling.
