I'd have to agree here. Only reason to do 40GE would be if someone said
they could have it shipping at latest during 2008, and we estimate 100GE
is not going to be until 2010.
40G would have made sense NOW, and not 2009-2010.
Of course, if 100GE for some reason is at risk to be delayed until
2011-2012, we're all in big trouble and need something to fill the gap
