Chatmandude, IMO that was a maag made by SPA to get the support of maoists... Now, that the SPA can go ahead and make the government themselves i.e without the help of maoists, I don't think they would worry about constituent assembly at the moment... After all these years of kursi deprivation, SPA would like to concentrate on their kursis rather than the Maoists who can execute SPA leaders anytime they come to power.
