I noticed that a 'few' of the current accessories can be used with either the new system. What about the RED DRIVES? Will these be fast enough with the FF35 or the S35? There's waaaay more to think about $ wise than just the bain price, after all, how much does it really cost to get a 'ONE' workable. It'll all come with time i guess but it would be good to get a more detailed list of exactly what current accessories from the 'ONE' will be usable on the new system.
