Orton mentioning his name this past Monday basically threw it out there in my opinion. How I see this playing out is he'll most likely cost Orton his match against Miz and later appear in the Rumble match only to have Orton come out and attack him from behind unexpectedly while he's making his entrance resulting in him needing help from the EMTs and be taken to the back. Orton will then join the Rumble and be one of the last 5 remaining along with Cena, CM Punk, Triple H and Wade Barret. Jericho will then rejoin the match seeing as he was never technically thrown over the top rope and eliminate Orton. Thus leading to a Orton Jericho feud. Now who'll win the Rumble? That I don't know lol. It's hard to predict a winner with so many guys capable of winning.
