for something like this to go onto the ballot, it requires the state legislature to consider it for 2 sessions consecutive.

This session has already come out with a "we are NOT going to touch this. We have MUCH more important stuff to consider." http://www.desmoinesregister.com/article/20090403/NEWS/90403010/1001

Which means 2014(?) at the earliest... (gretchen_marie, correct me if I'm wrong on this one)

It may still happen, given the stupidity at which some people act, but are people really willing to take away rights which will have existed for years by that point with nothing bad happening (see Canada, MA, etc.)
