WordPress 3.6 is not too far away, with the first beta already released last week. WordPress VIP blog did a very nice and very visual overview of the changes and new features in the release. For me personally, these are the highlights: log out notifications, better autosave, and a new look for post formats.
Things that I still hope to see one day in WordPress are: some sort of standard for post formats (cross-theme support, mobile app support, etc), and easier way of development and deployment across multiple environments (dev/test/live servers, etc). Regardless of my pending wishes, WordPress is still an awesome piece of software, which gets even more awesome with each release.
