Same "time frame," if you want to be technical. As we've seen, work
started on CentOS 6 and was suspended while the developers worked on
4.9 and 5.6. So, during the same time "frame," two point releases and
a major release all needed to be done. Sorry I didn't carefully choose
my words or go into "lawyer speak" mode.

And, has been noted, Scientific Linux gave preference to 6.0 and, as
of yet, still have not completed 5.6. It's not often that either
development team gets hit with a "triple whammy" like this. Scientific
Linux chose one path, CentOS chose another. Personally I happen to
agree with CentOS' choice here.
