There are many speculations and rumors that are going around, but you can check the main news here in bitcoin forum just above home or here "[urlhttps://bitcointalk.org/index.php?topic=2017191.0"[/url].  There are possibilities that there will be a split on block chain but we really don't know what will happen on that day until it happens. What we can do is to to be prepared on the day it will happen. There guides on the link that I sent to you on what you can do during the event for the safety of your coins and to prevent panic. The moderator will update us time to time as we come to close in after the month. Hope it helps
