AdWords Vouchers for Qualified Google Advertising Professionals In 2010

What is the situation with these?

I wish I knew.

For some reason, Google are being very secretive about them.

Here is a email I got from AdWords support when I asked the question:

Thank you for your email. The situation will be re-reviewed in the new year
and new promotional credits will be sent to those who are eligible.  I
would recommend you contact us when you need the new promotional credits
and your current credits have expired and we will be able to assist you.
