Onhwy61 is correct, there are numerous ways to get the data onto your PC or your Mac and most will be enjoyable. We should however all check back in 5 years and I believe most manufacturers still in business will have adopted, embraced and furthered the DSD format. The beauty of recording in DSD is that you are not limited to DSD or PCM. You could archive in 5.6mhz DSD (double the resolution of SACD) and output to any PCM format you choose, optimizing playback through your current digital player of choice. Most of the solutions out there as mentioned in Onhwy61's post require you to make a sample rate commitment up front be it 24/96, 16/44.1 or 24/192. There simply isn't a more affordable way to archive at the highest quality available.
As far as Korg and whether they will be making DSD recorders 5 years from now.....well, they have been in business since 1963, have been making DSD recorders since 2006 and when you look at what about $1500 gets you, it is really an amazing bargain. I have no affiliation to Korg other than as a consumer but as a method to record your music from an analog signal digitally, there is simply no better $1500 solution available. I am however always open to new ideas and equipment. Something may come out next week that addresses everything for less and since I am always glad to try something new. I would urge you to call your local Korg dealer and see if they have a MR2000 in stock available for demo to try it. Good luck all.
