My two cents:
The Saab 340 doesn't like ice. Effects performance badly.
The model at MEL airport was actually one of 5 which were bolted on to the roofs of VW Beetles and driven around cities to promote the newly formed REX not so many years ago. If you squint and use imagination it does look alot like a Saab 2000.
Rumours of the introduction of the Saab 2000 have been around well over 10 years. Its a wish list thing for the pilots. As Krusty listed, not really a viable option. Oh, and by the way, the Saab 2000 doesn't have de-ice boots that operate on "AUTO", you have to contantly press the button!
