(Thanks to Dave K for the tip!)
When the English version of Darius Burst Another Chronicle was first seen in the UK at an Electrocoin event about a month ago, it was said that the game would afterwards be going on test at the Funland, Trocadero in London. Then Funland unexpectedly closed. It took a little time but it seems that they found another site to test the game and that happens to be at the Casino Arcade, also in London.
From the thread Dave linked me to where fans have been following the test, so far the feedback is hugely positive, especially when it comes to the sound. There is also another thread on that same board with feedback, including some info about further location tests around the world, including one cabinet headed for Italy. Hopefully we’ll know about the US tests here soon (a poster in the latter thread says that two cabinets are in the US – if anyone has seen them, please let us know). From those threads I also found the following videos:

And in the Youtube sidebar of related videos to the one above, I noticed that 60Hz has posted a promo video for the EX upgrade that is out today in Japan:
