Well there is some information on github for the next hard fork:

"null" Account Balances

Balances of the null account and zeroed every block. Because any funds in the null account are inaccesible, they are removed every block and
the dynamic global property object is updated to reflect the actual totals. This will remove funds from the supply, slowing the rate of inflation.

It still isn't specific enough for my liking though!

You're welcome. I enjoyed the post.
