My 2 cents about the raid cluster.
What I think Turbine is doing is releasing the HD with a few glorified skirmishes(Big Battles) and keeping an instance/raid cluster for the next zone. As shown with RoI and RoR Turbine can't create the EXP+raids fast enough, so they release raids a few months later. This way they can put bigger price on the next small upgrade and If you remember forums were full with cries about the delayed cluster, so this time they just don't tell us.
I am not 100% sure on that it is just my thoughts and they can be completely false, but this suits Turbines style and it could work fine for Turbine as we will have to purchase both the expansion + instance cluster with the small update(like Great River and that With... thingy)
