Small OS updates like 3 are OK but you still have the same sound system, whereas with software based systems as well as getting many more features added, a new sound system can also be incorporated.
It is good to see hardware boards that can be updated, (All Wersi instruments produced since the company started in 1969 have had this capability, but even they pale in significance compared to the software based OAS instruments) however please remember that the updates are quite minor when compared to the updates you get on a software based instrument.
Enjoy whatever you play
