I'm not sure if the plan was to mention it here, but once it's released, I'll try to remember personally. Although with all the great people that follow this thread, I'm sure someone will beat me to it.
As for the new app being better than Labs, it will be regarding using the forum. I think the goal is to have parity with the website as far as post features which Labs doesn't have. As for the other features of Labs, some might not make it over, but they are thinking of trying to find developers to continue those features.
