Don't misunderstand me : it would be really good in my opinion, but they never say there will be a buff tracker in this patch.
There is a dps meter against the skeleton dummy, it's still a thing.
They said they are working on them not that we will see them this patch. It's actually not so easy to implement considering the huge amount of buffs/debuffs we might have. I've seen a few screens of the PC mods that provide this info but that will most likely not work on a Console due to fact the most players play on a TV set and the info would be absolutely unreadable because its to small (already a problem with a few other UI elements).
