This is a good question. In the past, the answer would have been yes. And it is still possible in the future. But at this time, it is my understanding that the Project does not have the resources to supply packages for all architecutures when -stable ports are developed. You can build them yourself, from the ports tree, or you may obtain them from
M:Tier, a third party organization that builds -stable systems and -stable packages for the convenience of the community.
