Top Camera and Hidakaya are not known to be reliable sources of information. Try National in Harajuku and Lemonsha in Ginza they are two of the bigger pro places in Tokyo. National always maintains an up to date list of currently films, soon to be discontinued and discontinued films on their site. I spoke with both the film managers (one of whom is a close friend of nearly 10 years) at the Yodobashi main store in Shinjuku and the Bic Camera across from the station, neither of them had any information about any thing being of the films being discontinued as of an hour ago. I am not saying you are wrong, but at least my contacts don't have any information about it.....yet. My friend did say that the instant film was selling quite well, especially since Polaroid's demise and was surprised by rumor.
