The problem with Orton interfering in an Undertaker vs. Batista match is that Orton has beef with both guys, and thusly would rather hit both of them. Now, that could lead to Orton getting a title shot on a Smackdown before facing Taker at SSlam, but then everyone would know that Orton was going to get shitkicked and wouldn't care. It seems they are trying to build Orton up to a longer Batista program, and I would rather see Orton just be there facing Taker now and doing the inevitable than doing Orton vs. Batista on a Smackdown and having both JBL and Taker interfere so predictably.
I'm not really wanting to see Orton vs. Batista in the first place, but since I know that's where it is headed, I'm trying to work with the situation.
