If i can say something. I suppose we could wait for a new openSUSE survey, as we did in August - http://news.opensuse.org/2008/08/21/last-call-for-opensuse-survey/ There should be a question about schedule - how should developement period take, or how long development schedule do you wish - whether 6,8,9... months etc. Result could show which period plan would be ideal for most users/developers.
Btw, i also prefer longer release time, for example 8 or 9 months. 6 months is too short.
