There's been the installer release candidate for the past month while now the number of release-critical bugs has dropped to 96. Of that count, 30 currently have a patch, a handful have a fix prepared or being prepared for upload, and another set of bugs are being ignored. Those interested in the full bug list can find it at Debian.org. There's also this bug list about Wheezy.
With this reduced bug count, it's possible we could see Debian 7.0 released in the next month. As for the new features, read what's coming new to Wheezy.
