That's just a news post from a tech site and nothing more.
That procedure , doesnt make sense at all.
Perhaps you should reconsider things a bit more.
There's even different NDA types (non-disclosure agreement) and dates for different persons.
Even more , there where NDA's and announcements in the past and no official release of a product (AMD cpu's for example).
You are blocking results for typical reasons and minor details ... and on the other hand you are permitting results done with a non existant board or a board that only friends and family of the company actually had , at that date.
Anyway that's my opinion.
At the end it's your call.
Your game , your rules.
