Could think of a couple of possible reasons:
1. The 125 and 400 line was never on the market. Beech had decided the support business for them was too lucrative to give up. The composite lines were being actively touted.
2. The 125 is very similar to existing Cessna products. Mind you so is the premier i guess.
Only guesses. Good news though, particularly for the US and more so Wichita. Good to see an old pioneering airplane builder not end up in Brazilian hands.
