In another official post by Erika from Nintendo, the redesign for the Miiverse will be coming soon on July 29. Due to the comment and posting restrictions that will be implemented on that day, all I can say is enjoy your freedom while you can.
As stated in other news, users will no longer be able to post on their activity feed and will be limited to 30 posts and comments together per day. Though the redesign was meant to keep Miiverse game-centered, it has been met with complaints by many who use it. Regardless, it will be happening.
