No, I think you're right. By making SSL the service used by signed-in users, the referrer will no longer include the query keywords.
When you search from https://www.google.com, websites you visit from our organic search listings will still know that you came from Google, but won't receive information about each individual query.
They can also receive an aggregated list of the top 1,000 search queries that drove traffic to their site for each of the past 30 days through Google Webmaster Tools.
That will definitely change the ball game.
For now, this only affects signed-in users. The full data will still be available for users who aren't signed in to a Google account. I guess we'll soon get a good idea of how many of our visitors from search are seeing personalized results and how many are not-logged in
