Well, after being lost in limbo all afternoon/early evening it appears that the viewfinders are actually in stock at B&H. They are also in stock at the Sony online store, with free shipping. I could have done without the angst.
Are you going to buy one?
Wait for your news about it... I have a nex-5, and there isn't a EVF for my camera, but a partner have a nex-5n, and he's thinking about the useful of it (because it's a very expensive article...)
