That is definitly not going to happen.
The F-50, although a large aircraft, well and truely makes up for the lack of an APU with many many other benifits to it's passengers, and they enjoy the aircraft. I've been in a Metro and A Brasliia and the F-50 has alot more passenger appeal. As for speed. Over these distances the time difference is nothing.
So you can put the rumour in the bin.
Never going to happen... Good try... but no, no, no ,no no.
