Well, it seems the Micro Ace Kiha 52 (0 bandai) motorized and dummy pair I ordered has finally been shipped, or will ship sometime next week. This run has been delayed considerably, with an original release date of March or so, but with the earthquake/tsunami, got pushed back considerably (I wonder why, coz I think this stuff is made in China). Here is Micro Ace's flyer for this particular run:

There appear to be plenty of kiha 52's left over from the previous run of a few years ago, but in more modern paint schemes with some having aircon, which appeal less to the above mentioned purists.
video, this is an example of the previous run, on a home layout:
