A feud between Cody Rhodes and Goldust is imminent and it's something that the WWE should give Dustin if this is how he wants to end his career. It's the least they could do for a guy who has given back so much to the company, ignoring the fact he had a brief stint in TNA, something you can't fault him for (although his gimmick there was apparently fucking terrible).
The feud between Rhodes and Booker should segway nicely into one between the Rhodes brothers, but I find myself having trouble picturing it as a good thing for Cody as it'd likely be at Wrestlemania. The feud between Booker isn't finished quite yet, but once it has then the one with Goldust could begin... but should it end at Wrestlemania?
Think about it. Goldust isn't a big draw, and frankly if he was to put his career on the line at Wrestlemania, I think it'd be easily overshadowed by this possibly being Undertaker's final appearance, but also close to the end for Triple H. That wouldn't be good for Cody either, and frankly it would be a step back for him when he should possibly be the one winning the Money in the Bank Ladder match (if they have one). It's like with Dolph Ziggler at last year's Wrestlemania being placed in that mixed tag team match. It did nothing for him, and really it began to spell the end for Morrison too.
Don't get me wrong, I do wanna see this feud happen, even if it means Cody once again doesn't have a legitimate title contender, but having it happen at Wrestlemania wouldn't be a good idea. Problem is, where else would could it take place and not make it seem like a fill-in feud? To me it'd have to happen at the Royal Rumble as this thing with Booker seems like it's basically done, something that COULD be confirmed on Smackdown. You can rule out it happening at the Elimination Chamber as Cody will almost certainly be involved in the Smackdown Chamber match, leaving Wrestlemania where he should be involved in a match that outlines his credentials of becoming World Champion in 2012.
