Again, speaking far from real business experience, Fujifilm should be not very clever to kill hen, still laying eggs - so to speak about unreasonable price rise.
Only if they are trying to go for all or nothing, like those ebay sellers listing $10 worth camera for $50 - if someone swallows price, they are good, if not - they don't loose much.
Imagine that you make widgets. You have a major competitor who makes widgets that are commonly considered to be as good as yours. Some people like your widgets better, some like your competitor's widgets better, but by and large, you are in direct competition.
When everything else is equal, retail price is often a major selection factor. So you cut your prices as low as you can and still make a profit, so that you can sell your widgets.
Suddenly, your competitor is gone. The first thing you can do is to bring your prices up to a level where you are no longer operating on super-thin margins. So that's a price rise for consumers. What choice will they have? Demand should, at least temporarily, outstrip supply, since they have their normal demand plus at least some of the demand of their former competitor.
Now, perhaps you have seen the writing on the wall and you realize that the overall market for your widgets is declining anyway. You are beginning the process of winding down your widget-making business so that you can put your efforts into other, more profitable and more importantly, more forward-looking businesses.
Considering that if you wind down carefully, you can keep supply lower than demand, you can charge what you wish. Just about anything. Some people will be turned off - but where will they go? If they refuse to buy, then they get nothing, there are no other widget-makers. So you can double, even triple, the price - who cares? People who want will buy, people who are upset won't, but you're winding down anyway.
In this case, you're not killing the goose that laid the golden egg, you've got a goose that's dying anyway, and you're just getting as much as you can for the last few eggs it makes before it ends up on the dinner table.
I would logically expect a price increase by Fuji in the case that Kodak quit the color print film business.
