Actually, I think the Cython branch with minivect support was in the end 
not merged, due to lack of interest/manpower to maintain support for 
vectorization in the long term (so it was better to not add the feature 
than have a badly supported feature).

My understanding is that Numba is based on minivect and not on dynd, so 
it's more of a competitor.

Perhaps Mark Florisson will be able to comment.
