Sounds very interesting indeed. Notice that Martin Harris said included with the Voice Expansion Pack(s) there will also be Registrations, OTS, and Multipads too. So for $200 for each Pack (not sure if that's MSRP or Street price) you'll get a multitude of PremiumVoices plus the others things mentioned apparently.

Depending on how good the overall quality of each Pack is, will needless to say, be the determining factor to their success. I can't see people just throwing their money away on a mediocre product with mediocre content. On the other hand, there will always be your dyed in the wool staunch Yamaha loyalists who would not only pay any price "regardless of content", but would also lay down their very lives for the big "Y" in the sky and would go down with the Ship if it were to somehow sink. Now that's devotion, eh? But if I owned a Tyros3 (which I don't because Yamaha forgot to attach 15 extra keys to it ) you can rest assured I wouldn't plunk down a handsome sum on 'anything' unless the product and content were worth it. Hopefully the Voice Expansion Packs will be worth it though. I like to see happy and satisfied Tyros3 customers just like the next guy. If the T3 had 15 extra keys Yamaha could have added one more to the list too i.e. ME! >> Nevertheless, I would have done everything in my power to try and fix those underwhelming Drum kits though. LOL..

All the best,
Mike
