Thanks to (M. H. D.) for this translation of the latest post on the Korg DS-10 blog:
It basically says that they are working on getting all the bugs found and fixed and that because they’re busy doing that, there aren’t going to be any new additions included on top of what they already have.
They’re fixing bugs as fast as they can find them, but new ones keep popping up, “There’s another enemy!” “There’s a scary one!”
He makes a funny reference to feeling like the snot-nosed Nobita-kun asking Doraemon for a fantastic machine invention to get them out of the fix they’re in.
They aren’t saying it’s not going to come out in July, just that there’s not going to be any new additions. July seemed far away, but now it’s closer than they thought.
Not a big shock really when you think about it as it is a very ambitious project overall.
