This will have 24 bit ins and outs. It's CD burning functions will be improved so you won't have to create an image file each time you want to burn a CD. It's external case has been redisigned to make it smaller but it doesn't seem to offer anything really new from the 1680.

I hold that Roland have smelt the cheese and given users the option to record uncompressed audio on all 16 tracks- now that would be very nice!
