Heath Slater's exemption from 2K15 is definitely a bit odd. Despite his lowly jobber status, Slater is still a vital part of WWE's roster, appearing on television every single week. WWE needs guys like him to oil the wheels of the main stars. 2K15 could do with him too, using him as an easier opponent for the inexperienced gamers to beat. He'll surely be added in the next round of roster reveals. He was in WWE 2K14 and there's really no reason as to why 2K wouldn't use him again this year.
32. Bo Dallas
We do Bo-lieve that 2K will be working on Bo Dallas' character, but whether they complete him in time for the roster deadline is another question. We kind of get the feeling that he might just miss the cut, which would mean he'd be released later in the year as DLC. However, many fans are convinced that he'll make the roster, so we'll include him here. 2K would have certainly felt like they had to get him in the game. When he first debuted he appeared to have a lot of up-side, WWE looked like they had plans to take him up the card. That's already hit the wayside though, with Vince McMahon reportedly giving up on Bo's potential.
31. Stardust
Yes, Cody Rhodes is announced for WWE 2K15, but there's no Stardust. That will surely be corrected in the next roster update, it should merely be a case of 2K programming a new skin over Cody's game profile. It's essential that this update is made, Cody is history and Stardust looks to be sticking around for the foreseeable future. Rhodes first started portraying Stardust back in mid June. At first it looked like it might be a good opportunity for the wrestler, but he's since became just another silly gimmick.
