I personally don't think a port of OS4 to pegasos 2 will happen as Hyperion/Eyetech are too much involved and they still believe in ArticiaSux "feature". Moreover if peg2 were available for OS4 it will a dry lost for Eyetech. So I don't think it will happen.

But if it would happen I would have mixed feelings :

1 Bad because direct MOS concurrent (at this time) has now good hardware

2 Good for bplan to earn a bit more money
