I think they have been discontinued along with Cultus VXLi to give sales boost to Swift. I seriously doubt that Suzuki will release another new model/series so soon.
FYI: You can still buy LXI, Eminent & VXLi Cultus in some show rooms & car dealers without any premium and ready delivery, Last I checked Cultus VXLi was avaiable for VXRi Price + 55,000 that makes 845,000+55,000 900,000 a good 17,000 less then for the company sold it for.
