Will this change with time? I know numpy, pandas and matplotlib are likely relatively large projects, but my assumption is someone will likely put together data analysis / matrix math libraries to perform some of these functions.

I think Julia (http://julialang.org/) might be a better alternative to Scientific Python than Go. I'm not sure you can get the same flexibility/expressiveness you get in Numpy/R/Matlab in Go.
