Tell them that the majority of incompatibilities will be taken care of 
by an automated translation mechanism, and that the 2.X range will be 
maintained in parallel with the 3.X range, with features backported when 
it is feasible to do so, so there will be no *need* to migrate to 3.X 
until *at least* 3.1 (which will likely take us two years into the future).

You might also remind them that Microsoft have continually broken 
backwards compatibility, and that this is a one-off deal that will make 
Python better and more consistent (not that they'll be interested in 
that, since they seem to have closed minds).

Finally, look for Python users who have migrated from Matlab (of which 
there are many) and get their opinions on why. I have used C# on a 
couple of projects now and it's an OK language, but it can't hold a 
candle to Python, which is now firmly in the .NET environment with 
Microsoft's IronPython open source implementation.
