Hi Zoran,
Don't know what version will be shipped in US, there is a good chance it will be an updated one as Kobo plans to release an upgrade next week (link
here).
As for copying books on an SD card directly, it works, I've tried it under linux (added some epub files onto a blank SD card, inserted the card into Kobo device). I didn't try to mount Kobo device itself (in case you don't have an extra SD card), but I believe it will work as the device is mounted under MS Windows just as any other USB storage device.
