I received my PSR910's today and spoke with Steve Deming at Yamaha regarding playing Tyros3 styles in the 910.
The 910 does have the same mode as the Tyros3 to play using the new Guitar mode. So, if you load Tyros 3 styles into the 910 they will play perfectly unless some of the super articulation sounds that are in the Tyros3 are not present in the 910 and in this case, the 910 will pick an appropriate other sound in its place.
