This saddens me, and I suspect the future Trello will be a much different animal from what it is today. It could be better, but my gut says not.
We've have been exposed to JIRA through external suppliers and that has been enough to make him on his edges now.
Personally I don't think much will change, at least in the first year or so until the contracts of the original developers lapse and they can move on to new things.
