Interesting - I hadn't realised that people didn't know there as a problem.
I might be in a slightly unusual situation because I'd not been following this all that closely - I remember the original announcement, didn't have PoE switches at the time, have since got some for other kit, then thought "A ha, I shall get one of those nifty PoE hats I remember hearing about", then found I couldn't. Then there was some Googling, the El Reg piece, then this forum thread.
I had looked at the blog to see if there was any news of sellouts and more availability (there was, IIRC, pretty much a running commentary when the Pi Zero first launched and sold out everywhere), and there wasn't any sign of anything, which is why I'm quite keen on there being something to catch anyone else who follows the same sort of path, even if you hadn't been ready to post all the gory details.
Clearly, anyone who's got one of the first batch and had it not work for them knows they've got a problem, but for those of us who don't have one at all it just looks for all the world as though it should be available, but has mysteriously vanished.
Anyway, I shall look forward to the blog post, then hopefully a v2 in the not too distant future.
