They were briefly in stock about 3 weeks ago. At that time a FT rep siad it was authentic old stock. I'm guessing today they've found more? I don't know of FT selling fakes as authentic but that's all I've got.I saw that Sony said that they did not make a VTC5 yet, that those marketed as such are not real, just FYI; I say batteries are not something we want to flip a coin with.

Heck, it might be in a back room in China or sitting in US customs but no way to really tell. 
I put in a request for the tall skinny bottles though (same shape as a mod). Hope they come through with those.
