LOL at everyone thinking their z97/77 boards are going to get an update and the motherboard manufacturers aren't going to use this as an excuse to cash in on people buying new boards.

Last I checked, Sabertooth Z77 hit the stores in, like... 2013-March'ish, and was sold for quite a while after that.
So I would have to say that there are still many of those Sabertooth Z77 boards inside of warranty.
Not that I don't expect Asus to totally give said board owners the middle finger, because why stand behind your own product?
