WWE has changed some of their originally intended plans for the future. Originally, Randy Orton was going to switch to a baby face, as the company had even informed their merchandise department to work on some baby face items for Orton for down the line. That appears to be off the table at this point, with the current plan having Orton staying heel for the time being.
As far as Sheamus is concerned, while the original plan was to push him as one of the top baby faces in the company, it appears that they are starting a slow build towards an eventual heel turn for him.
