It appears that at least for right now, WWE is going with the assumption that The Rock won't be back next year as a short-term character as he has been for the past three years.
given to a major licensee this past week, they were told not to produce any merchandise involving The Rock. They were told he could be used as far as a group shot of Superstars goes but not to produce anything specific because he was not going to be featured until 2015.
This was taken as a sign that The Rock is not going to do WrestleMania XXX. We still don't know if Rock has said this or not to WWE officials. It could be that an assumption was made over the call to not merchandise him individually.
