-It is looking more and more like WWE will move from Spike TV over to USA Networks. There is already some motion between both sides which would indicate that this move is becoming more and more likely. Also, if Raw is to move to USA there is a good chance that Smackdown! will be dropped from UPN and will also end up on USA. This may mean that Smackdown! will change nights in the future and may even become a live show after the change.
-There is still talk of turning Randy Orton heel in the future and this may also play into the fact of having him go against Undertaker at WrestleMania 21. Since right now, both Orton and Taker are considered "babyfaces" then it would make the match more marketable and also set Orton up with a possible match with Batista in the future.
