Agreed. Yes those motors (if the lens is desgined for it) are WAY faster. And yes DA* lenses should be upgraded although I suspect that FF lenses will come first.
Fortunately for you, both lenses you wrote about are both FF lenses. DA*55 though may or may not be kept as it was designed to replace FA85 as a portrait lens. I dunno what Ricoh intends to do with it.
IMO the 55 is a nice alternative to usual 50mm but it may come later.
The DA*200 is an FA200 in DA* clothes so they may or may not reuse the optical formula, or chose to upgrade it to modern standard (if it isn't now).
All current DA lenses covering FF can be upgraded to modern DC motor. The question is: should they upgrade or should they rework them ?
IMO a number of them will get reworked.
