There haven't been any firm dates set beyond what we know now:
The RC will expire on June 1, 2010. Starting on March 1, 2010, your PC will begin shutting down every two hours. Windows will notify you two weeks before the bi-hourly shutdowns start. To avoid interruption, you'll need to rebuild your test machine using a valid version of Windows before the software expires. You'll need to rebuild your test PC to replace the OS and reinstall all your programs and data.
So, you can see that you'll be able to use the RC for nearly a full year.
Hope this gives you some insight.
