Here's what I see and take this however you wish...
The current shifter offering from Fanatec is the CSR shifter. This shifter is almost made entirely from plastic. The only difference between it and the previous shifter is the knob itself. It's important to understand the relationship between what it's made of and what it costs to purchase. It's likely these are not expensive to produce. They are $59.95 before shipping.
Now, with this in mind... Remember the photos you have seen thus far of the CSS. It looks to be made almost entirely of metal. Metal is expensive to machine and expensive to work with in general compared to plastics. Actual machining is involved in order for it to work precisely, you can't just injection mold it like you can plastics.
Taking this one step futher... Look at the cost of the ClubSport V2 pedals. Metal, fairly precision, machining is required, lots of parts involved as well as assembly. (much like a CSS) Their cost is $249.95.
To finish up... I would estimate the cost of a CSS, if released, to be right around $250 if not higher. I feel this is the primary reason it has not been released. The price is not competitive, despite community desire.
That's just my couple cents.
