While it's not impossible to get another update, i really would not expect it. You gotta understand the idea of "priority" doesn't work how you think it does. The people who are able to deal with this issue will not be dealing with many things outside their speciality (ie the people who are going to be working on this have absolutely nothing to do with balance, content generation, art design, economy, stat analysis .etc). And while there are special priority jobs that must be done, this is almost definately not one of them, and on the other, typically non prioritized list. Everything on this list is important and must be done, but it's usually up to the people working on them to decide the most efficient and best way to tackle them. We've allready been told that they have reproduced this issue in house, and that is very signifigant information, it means they've allready put in some of the most signifigant work in diagnosing this issue. At this point it comes down to how complex it is to nail down and fix.
Even if there was a priority on this, knowing what it's above and below would not be useful in determining much of anything, and bliz would never disclose this kind of internal information. If we do get an update it will likely be after a patch that has a fix in it, to see our feedback. Or, if there's public declaration of the patch leading up to it's release, there might be feedback saying that there's a possible fix en route in the patch.
That said, it's still not impossible to get feedback before then, just I would not expect it.
