Thank You Jim,
That is great news! I can't wait to get my upgrade! Do we know of any third parties working on anything like this?

PS Technik in Munich is working on a optical Viewfinder which should work on any PL Mount, it will work with a 50:50 beam splitter so you´ll loose a stop. i think it´s still under development, didn´t see anything on the last trade show in Sept. at PS Technik booth.
