WWE signed the last guest host before Wrestlemania 26 just this week as Pete Rose. Prior to that, there was speculation that Stone Cold Steve Austin would be the final guest host on March 15.
However, not only will there be a guest host until Wrestlemania, there are apparently plans to continue the guest host gimmick for Raw into the summer. There have been rumors that the The Rock would guest host a series of shows over the summer.
