The vocal posters of this forum aren't the majority of 1/6 buyers nor the majority of worldwide Star Wars fans. I have a feeling that we will probably be seeing creeping up prices from both companies but it won't hurt the market and they'll always be enough people to pay the price eventually.
It used to be that people would see a product on the shelf for the first time and be able to buy it. It wouldn't be sold out months before it shipped. If high prices keep figures available for awhile it could keep desirable items available for longer and thus bring new (albeit wealthier) members to the hobby.
They might not be the majority but can tell you that collectors as a whole won't pay these prices. I know someone who has a store and sells SSC stuff and he has said all his buyers are slowing down, him included. SW is like gi Joe, won't matter how many new movies they pump out, the line will not pick up steam with new collectors and certainly not wealthier ones.
