There was an announcement on the Roland Germany forum reported at Roland-arranger.com -
http://www.roland-arranger.com/smf/index.php?topic=819.msg4844#msg4844

that seemed to officially announce the cessation of production of the G70. Roland Germany sure seem to be on the ball, being able to STILL manage to get OS updates out of Roland Arranger R&D to fix obscure bugs, and have generally been less opaque when it comes to communicating with the customers over there...

So, take it as you wish, but this SEEMS like the end... at least of production. That's not to say they can't restart it if demand suddenly increases, but that seems unlikely without a new OS to kick start it again...

In the meantime, count on most of the Roland dealers telling you exactly what they feel like, facts or no... You can hardly expect them to tell you something is no longer in production if they are trying to sell you something! Especially without a replacement for it, yet...
