Who...stopped making what, and "not wanting to be in the market"!? There may be a much lower demand in the market for 400X, but Fujifilm, the busienss, is not going anywhere from the market that we can see. Retailers sit back and scratch their balls and wonder why shoppers don't come through their door. The reason has been repeated umpteen times in the print media: "the prices are too high", "gouging", "they quote one price then jack it up when you come in", etc., etc.
The Fuji corporation have stopped manufacturing Fuji Provia 400X so you will soon have nothing to complain about.
