Thank you all for your interest and support of Combat Tiers!
Aside from the new packaging, the product remains the same; they can be combined with previous sets and made from the same durable transparent acrylic. The new box comes with two Combat Tiers, consisting of two base platforms, two middle platforms, two top platforms, two four-inch extensions, and two two-inch extensions. You will be surprised by the versatility of Combat Tiers, I have received many photographs which showcase unique combinations and have been astounded by their creative applications.
If you are attending Gen Con, please make sure to visit me and pick up a set as I will have limited supplies on hand. You may also place your pre-orders and the good folks here at Paizo will be shipping them out as soon as they arrive! And, yes Combat Tiers will soon be available at your FLGS!
