Google is killing off Adsense?

Holy Cow!  Google is killing Adsense.

I just got this email today:

You have received this mandatory email service announcement to update you about important changes to AdSense on your Google Sites account.

So I went to the Adsense website and I got this terse notice:

Sunsetting AdSense

Some important changes are coming to AdSense on Google Sites. By August 30, 2013, it will no longer be possible to make updates to AdSense on any of your Google Sites.

No change is required on the part of AdSense users. Any ads that you currently have running will not be altered or removed, though you’ll be free to delete ads yourself. However, it will no longer be possible to edit or add new AdSense ads to your existing site or to new pages.

There is no other explanation.  There is no indication of what if anything will replace it.  Inquiring minds want to know!
