Heck, I just read that Ethicon actually used part of its own $ to fund Verb. So if its Microline that would be a "hell no" on them partnering with Titan.
Ximedica is pretty well known for their "user experience" work. Their biggest contribution to SPORT was the software that is is running and the ergonomics of the device. In my mind, Titan working with Verb would mean throwing away the last couple of years of software development on the robot by Ximedica, so IMHO the Verb connection is very unlikely.
Speaking of software development for the robot, this guy has a nice write up on his LinkedIn profile of the software development life-cycle for SPORT:
Looks like they made some major improvements when they went to multiple indications. SPORT is now running the same real-time OS that runs inside the engine controller of almost every car manufactured today.
