as I told before I´m no tech but when I understand correctly the processor of O should handle the Kronos OS and HDD should not be a problem ....
after thinking over I read again Jerry´s post on behalf discontinued production of OASYS:
I'm posting this on behalf of Korg Inc:
There have been a lot of inquiries and dialog regarding the status of the OASYS, and we would like to explain the OASYS current status and future. It is true that OASYS production has now finished. A number of distributors still have stock and so sales continue, but you will see this situation change across different markets as time goes by. We always knew we were creating a more limited-market product for a smaller group of discerning musicians (you!) and we are pleased to have been able to deliver you this elite music-making tool. You have a wonderful musical instrument with which to realize your personal expression, the finest we have ever developed.
We have recently released some system tweaks/bug fixes and have plans for some more ongoing sound support, like the new sounds we just released.
We constantly get ideas/suggestions/requests for more features for the OASYS, but we cannot promise that any of these can be delivered. The current world economic situation affects us all, and we have to adapt our plans and channel our resources to best navigate these uncertain waters. We are proud of the OASYS and all that we have achieved with it, and thank all of the users and owners who shared in our vision of this superlative keyboard.
As always, we will announce further support only when it becomes available.
this turned out to make me more angry.
I understand when they don´t build units because they won´t sell O´s.
I understand when they build newer products with a lower price for the mass market to earn money even when they incorporate the synth engines we had to pay for.
But I cannot accept and understand that if Kronos OS would be handled and could be overtaken to OASYS as it seems to be a kind of OS 2.0 and disc streaming is possible when Korg is not delivering an update to OASYS users. In this case I feel deeply ripped paying for the O and the expansions and listening to Korg´s statement that they are proud of OASYS and what they have achieved with it and that they would say thank you to us users who shared the dream ... hey we´are still sharing !!!!! Of course I know that there comes the time that due to processor etc developments the O will not be able to follow newer technology but as long as it´s hardware is sufficient ...

As I´m not expecting a statement from Korg about updating possibilities I don´t know if we ever can clear this point. Until now I thought Oasys processor and drive could´nt handle Kronos options.
At last as in Jerry´s statement told we will get information if/when further support is given ... maybe an update maybe we never get that magic email from korguser.net telling about updates ...
