Thanks to 6thCCU for pointing this out to me under the Roden B-36B topic. Anigrand is to release a new 1/144 XC-99, though the release date has not been released. Hannants shows the forthcoming kit on their site but a search of the internet unearthed no additional information. Nor did I see anything on the Anigrand website confirming this release. Given that Hannants has it listed, this doesn't appear to be a rumored release but the lack of further information makes the status of this project hard to determine. I'm not familiar with Anigrand's practices regarding information on new releases so I'm definitely open to education from more experienced Britmodelers.
