Hi - long time lurker, first time poster.
Saw this monster at Taito Station in Akihabara today:

Unfortunately I did not notice the sign forbidding photography, so I accidentally took the pic, before the gentleman instructed me not to do so any more. There was also a sign telling of a network test lasting until 4th of July or something of that sort, but that did not make it to the picture.
I tried it for a credit, felt mostly identical to the X360 version. The cab had Sanwa stick and buttons, which made it a little hard to tell, and caused a bunch of mistakes.
