Something interesting came in today, and is simply from a phone call with a little bit of information regarding older Hive Guard and Tyrant Guard models that needed to be updated to the new match new models.
Please remember that this is considered to be a rumor.

I spoke to at gwhq on the phone today and informed me that the 50mm round bases would be available separately asap and are aiming for february/march time. They will be available from the online store in the same section as the other bases. Great for updating the older hive and tyrant guard models.
