Yes, I also had a look at these product sites and read many postings at the Yamaha XG-users forum, XG-Central forum and Michael Banz's Discussion board. Some more features of these new sound-modules are:
-more effect units (up to 6 Insertion-effects)
-possibility to use user-samples
-built-in sequencer (MU2000)
-take more PLG-cards
-bigger wavetable-ROM
-digital out
-XGWorksV3 in packet

You already can buy these products in Japan also like XGWorks 4!
So you only have to find a vendor there over the internet and order it - if you can read japanese ; ) or just wait until next year. I'm sure, Yamaha plans to bring these modules to america and europe with the next NAMM.
