I don't want to ruin it for anyone, but I think it would be best if we kept our expectations low for the next era. If Timber goes #1, it would be great if she released an album soon. But who knows how long the wait is going to be. It may turn out to be much longer than that, we were waiting for Warrior for quite some time too.
Edit:
We also don't know whether she does or does not have real issues with Luke. Who knows if her next effort with him won't be a bump in the road that they'll struggle with.
