Actually the 0x129 microcode was released yesterday, now it depends on which motherboard you have and how quickly they release a bios that packages it. According to Anandtech Asus and MSI did already release before Intel made the announcement. I see some for Gigabyte and Asrock too.

So, not out yet. At least not fully.

If you prefer being right, rather than just accepting the extra information, then sure let's go with that.
