Who's to say that they won't launch the single dimensional model overseas, while working on all of the "other" models for US - FDA launch? They have to have the FIRST procedure as a turnkey unit, with other procedure kits as additional justification for a more useful medical product to get hospital budget approval. I think this is a likely path to launch. And it would meet both the revision and the "padded" timelline theiories. Overseas surgical minimum requirements are less strict? No? JMO. Regards.
