The Fuji case has much more to it than just "almost nonexistent amateur market" or "no one buys their neg films" or "no one buys Sensia".
To me, it looks like Fuji is in chaotic state because of the current Japanese economical state. Look at the Toyota.
If we compare, it looks to me that Kodak is really discontinuing products that are used much less than their other products, making a decision based on sales number to protect the remaining products. This is how things work in a somewhat healthy business model.
On the other hand, I'm sure Sensia had quite a bit of users. I can't back this up with any evidence, as no one here can. Only Fuji could really know.
Fuji has made many contradictory statements. They have reported increase in film sales and increasing commitment to film, which cannot be seen in the recent activities concerning the discontinuation of almost half of their products in a short time.
Then again, as I have read in many sources, heard here at APUG and seen by myself, Fuji has tremendous problems in their supply chain. Many if not most Fuji films in Europe were all sold out this winter, and this happens every now and then. So, even if you wanted to buy Fuji film, it's hard to buy because 1) you cannot know if this product is still made or discontinued, 2) if it's made, it may not be imported to where you live, or even the whole continent, or even the whole world exluding Japan!, 3) even if it's imported, it may be sold out because it may be imported much less than the demand(!)
As said by others, the "pallet" thing is pure bullshit. Everyone knows that importing stuff today is cheap if done right. It's a matter of bureaucracy, and Fuji's current exporting scheme is a pure example of insane bureaucracy which will cost Fuji's life if something is not done soon. In reality, there is no minimum limit for export, especially for film which doesn't expire quickly like food. This is one of the easiest problems. The fact Fuji cannot solve it, shows that they don't have the time to do it, and if a company doesn't have time to sell it's products in a tight situation, what will be its destiny? In a tight situation, the only sustainable way to get some money is to sell your products aggressively! Fuji is doing the opposite.
All in all, there seems to be more demand for Fuji products than there is supply! In a healthy business situation, this is a sign of a great success, but in this case it's a sign of very dangerous situation inside Fuji. If they cannot sell their products even when there is demand, what will happen to them?
We are now seeing a series of consequences to these internal business/marketing problems. What it looks to me, products that are not niche products at all, gets discontinued randomly as stock / master roll runs out and there is no funds to continue that product in question. It's completely different than to make calm decisions based on sales numbers.
