Here's an interesting comment thread on the topic from some months
back:
http://thewoodwhisperer.com/a-sawstop-killer/

Some interesting tidbits in the comments, such as anecdotal 'evidence'
of the big tool companies working together to develop a SawStop
alternative, expired prior patents that would fulfill the anticipated
performance requirements, etc.

I'm betting the performance requirements pass, major changes are made,
and SawStop is out of business in 10 years. Hubris, and all that.
