I would expect PyTables 2.x to return numpy objects, even if they were originally stored as a numarray. But then again: I am so new to pytables and numerical python, that I have never even knowingly used numarray... I guess if people don't want to change existing code, they might as well continue to use PyTables 1.x. Those who want to use PyTables 2.x are actively developing or maintaining code, are likely to migrate to numpy anyway (if they haven't done so already) and are likely to have older datasets around that they may want to access with new code.
