First off the RC doesn't expire until March 2010..
One place you said, March 2010, the other Oct 22 (2009?), at least that is what it looks like to me. (But, I do get confused easily)RC as it will be fine to keep using until Oct 22
So what is the timing here?.. and those who don't can either continue using the RC as it will be fine to keep using until Oct 22 when the GA goes live.. OR they can get the RTM through the usual methods as I've no doubt that it will be leaked shortly after it goes live..
what are you going to do?
