You know about as much as the rest of us do on BF deals. My recommendation would be to check this website regularly which is an aggregate for linking all the BF store deals as they are released:

But I will say this: as a long time Black Friday watcher, I find Cyber Monday sales better deals when it comes to GPUs. However, it is rare to see upper end GPUs get massively discounted on either sale date.
