Since Scott has a Tyros2, it would be to his benefit to take it to a music store that has the S910, and, using headphones, he can A/B the two instruments to his own satisfaction.

The Tyros3 sounds different than the Tyros2, otherwise I could use the former to compare voices with the S910.

I can say the SA Jazz Rotary, and SA Rock Rotary sound pretty darn close to the Tyros3's...I'm not sure if the Tyros2 had those voices.

For gigging, the S900 and/or the S910 are terrific, but as I said earlier, Scott is used to having three voices layered in the right hand...the S-910 can only do two.

That might be a deal breaker.

Also, if you're used to having aftertouch to control sounds, the Tyros2 has it...the S910 does not.
