According to PWInsider.com, while anything can always happen in WWE, Vickie Guerrero's appearance on Raw this week was said to be her last with the company.
Vickie actually informed WWE officials prior to WrestleMania 30 that she would be leaving the company, but she decided to stay a little longer and finish out her run.
It's being said Vickie is leaving WWE on good terms and simply wanted to move on to the next stage in her life. She could, of course, make special appearances in the future.
As for the Eddie Guerrero references on Raw this week, it's being said Vickie had some creative input as to how her sendoff would go down, and she wanted to do some type of Eddie tribute, which is why she did the Eddie dance, came out to his music and more.
