Why the Tak .965 ep's?

Is there a particular reason why Takahashi continues to make .965" eyepieces when practically the entire rest of the astro world has gone to 1.25" (and 2")? Some benefit that you can't get otherwise, or is this another "that's the way they do it in Japan" thing?

Just curious...

Points which come to mind (not necessarily theories or reasons why):

At 42 degrees afov, there's no need for the 1.25-inch format. (Indeed, the two HI-Or models, with their subdiamter negative field lenses, need even *less* diameter. Imagine a 0.4-inch format!)

Less bulky; lighter in weight.

Slightly less lightpath "eaten" by the smaller format (vs. comparable 1.25ers).

Converting/adapting them to the larger format would increase cost.
