They are tweaking the main homepage and logged-out page - tweaks will also come to the logged-in page (which you see once you've entered username and password), eventually. The Horizon sitescheme is tweaked a bit, also. MyLJ will apparently no longer have a link, except in the sitemap.
They will shortly introduce the new Vertigo sitescheme in public beta-testing. It is visually similar to Horizon, but instead of having all the links to friendspage, memories, userinfo, scrapbook, settings, etc. in dropdown menus along the top, they will be as textlinks down the left-hand side, just as in the oldest sitescheme Dystopia.
In the near future (a month or two) they're planning on doing a purge of livejournals that have been deleted for more than 30 days.
There will be a limited-time sale of permanent accounts within the next few months. Permanent accounts are in essence paid accounts that never expire, but with more userpics (137) and more storage-space (10 GB) in Scrapbook. Last time they had a sale of permanent accounts, the sale was open for 24 hours and the accounts cost $150. I expect the exact time of the sale and new price of the permanent accounts will be announced in news a few hours before it opens.
For more details, see the news announcement.
Edit: They are also planning to introduce voice-post numbers in a few countries other than USA.
