The Windows 7 Team Blog officially announced the availability of the Windows 7 Release Candidate this morning:
As we previously announced, today the Windows 7 RC is now available for anyone interested in giving it a spin! Typically, a release candidate is the last development milestone before release to manufacturing (RTM), signifying that engineering and development have made significant advancements and that the code is entering the final phases of testing.
