If you happen to be in France the days of Feb 8 - 11th then you can attend the v6 World Congress event happening in Paris. I would not be surprised to see some announcements coming out of the event. Though at this point I am not sure if IANA is going to wait much longer to announce the IPv4 pool is officially depleted and it is down to the RIR pools only. Given the run rate that APNIC is going through addresses they might not make it before reporting 0 /24's out of their current allocation. I suspect that IANA has already given them their /8 block if not two and they are all waiting for the right moment to announce things for maximum media effect.
If you are in the US and want to attend one of the premier IPv6 events stateside then check out the Rocky Mountain IPv6 Task Force 2011 IPv6 Summit. Scott Hogg puts on a wonderful event and has an impressive line up of material and sessions.
In addition, later in 2011 will be events from the California IPv6 Task Force, the Texas IPv6 Task Force and others. I will post more when those dates get closer.
