"Batman: Gotham Knight" anime short done by Bee Train?

I came across a couple of reviews when scanning Google News for any "Bee Train" alerts. Details of what I found are on the thread in Bee Train Fan forum, but to sum up:

- Hiroshi Morioka (.hack, Tsubasa) directed the "Field Test" segment (which ANN says has a "bishonen Bruce Wayne"... *chortle*)
- Only two reviews actually say it's Bee Train; there's nothing on their official site or ANN (ANN says Production I.G. was one of the production companies)

Anyway, looks like I'll have to rent it sooner than later so I can confirm for myself.
