These days it seems we can't be told about anything without some PR person waving an NDA form.
In recent months we've been asked to sign an NDA covering products we'd already seen at a show in the States, and just had an email extending the NDA date on some new kit we were shown at the Toshiba show the other week. Don't panic, it was just new laptops!
The best NDA story to date was the pan-European event in Japan where you had to sign the NDA before you were let into the press conference, and all the various countries' PR people were responsible for ensuring 'their' journalists had signed.
Except the French journalists didn't, as the embargo date was just after their magazines came out, and they didn't want to be scooped by the Germans. Honestly...
As a result, we sat through a long product presentation, during which photography wasn't allowed, only to be told at the end that the NDA no longer existed following some frantic behind the scenes PR squawking. But no, we wouldn't be allowed to take pictures of the products we'd just seen. And now the factory tour...
You couldn't make this stuff up...
