Now . . .here's a teaser thought: So, what happens if the ES is: 650 or 750? What number will push you over the edge to cancellation? Back in the LOTR days (many of the SW fans may not have been around), a 750 ES for Stone Trolls, OG Balrog and Cave Troll would not make people rush to buy. The ES was announced, but I'm pretty sure there was a lot of in-dealings, cancellations and after market change of hands. Fast forward to today and we know what prices each of those can command.
Now . . .as for this big hunk of plastic, foam and metal item . . .How much stake can the SW community put on it? I can tell you that none of the SW PFs have maintained their value to date. If we use history, regardless of the ES, this bad boy may not be seen as worth $800 in the long run.
Then again, SS has not released any ES of 50 or 100 on anything. If SS was smart, that's the direction I would take to ensure a sense of eliteness(?) among SW collectors.
