Post Release and Pre v3 - League duration?

With the MOR release events winding down, what can we expect for the new leagues that will be spawning? Will we still be having the 1-week duration that was put in place during the v3.0 release countdown? Or will we see the re-instantiation of multi-week (i.e. four-week) leagues?

My preference is the 4-week variety, as I get more "bang for the buck". I also like the fact that it's harder for anyone to get a perfect record, and that tiebreaker points become less of a factor.
i want league game come back in 3.0, but i think its dream only...........
