Pure speculation on my part follows!

What has changed :
1)The Outlaw folks have learned a lot about how not to do things. This learning is often more valuable then what you learn when something goes well.
2) The Trinnov folks are going to be very motivated to show that their software is not the problem and may put in that extra effort to get it right this time. They will want to take some of the Audyssey market share and get their software into more products. Big bucks can be made there, a few dollars times lots of licenses is way better than more dollars for far fewer licenses, look at Microsoft.
3)The new manufacturer will be very interested in proving they can get it right. They likely want more market share for building electronics and pulling this off is going to give them credibility (if they need it). They'll make money working with Outlaw but may make far more money if this results in larger market share.
