Fairchild Dornier was developing the 728 prior to insolvency in early 2000's. Could have been a competitor to the Embraer. Apparently both project teams had links to the failed Indonesian regional jet.
I don't think Fokker will ever design and build a new or updated aircraft again. Fokker Elmo appears to be one company that rose from the ashes.
Regional jets are a good way to make a small fortune (from a large one )
