I'm not an engineer, but I definitely get that impression, and if deep pockets like ISRG can't do it quick, then I am not that not worried about the delay in terms of competition, and certainly not TRXC. Is there even a start-up company around that targets and does what the SPORT is about? If ISRG can't do it quick, I like to think we're still way in the lead. And Ximedica seems to be very good at what they do with deep pockets behind them now.
