The basic version of the 728, referred to as the "728-100", would have been followed around the end of 2003 by the 728-200, which would have featured an extended range capability along with a higher payload capacity. In the weeks prior to the company's insolvency, reports emerged that work on the 728-100 had been abandoned in favour of the more capable 728-200. Development and marketing of the stretched 928 model also continued. However, the 528 ultimately received little interest from the airlines, leading to it being quietly removed from the family plan.
