Undertaker Rests in Peace?

How would the WWE look without the Undertaker? I've been thinking about this for several months. I've even dreamt about the WWE introducing alook-alike and continuing the legacy of Taker.And lo, here comes the surprise! The Undertaker is banished from the WWE. I'm sure nobody expected this to happen.People who have been "firrrrrrrrrred" from the WWE have come back, among them Chris Jerrico, JBL, Jim Ross etc. So, will the Undertaker ever return? Or has Taker retired for ever? He isn't getting younger anyway.One day or another, the Undertaker would not wrestle anymore. Even people that never followed pro-wrestling knew the Undertaker. No wrestling fan could ever forget him.If this is Undertaker's true retirement, let him RIP!!!
