Fairchild was going to stretch the Dornier 328 into the 428 and 428JET but saw no market.
Saab 2000 was a great plane, But then again so was the BAe ATP. There is a reason they went bust. To make a comeback... that takes balls... and for that, I applaud Saab!
A little off topic, Fairchild Dornier also canceled the 728... I am surprised Bombardier didn't jump on that when they had the chance. C-Series would have been on-line years ago competeing with Embraer, as opposed to Embraer having a huge head start in the mini twin market.
Speaking of mini twin market... I also hear the Fokker 100 is making a comeback?!?!?!
