Google Chrome Team: "Ah snap, and we just dropped WebKit!" Edit: It's a joke, guys. :/
Nothing in there was particularly unknown as far as I know – Webkit 2 has been around for a while, Blink wanted a different direction on much of the newer architectural decisions IIRC.
Speaking of BLINK, Dallas based IIICTECH has been using BLINK for years. They're getting trampled by both Google & Microsoft. So mutch for having a good idea & having a far shot at owning intellectual property... like a trademark. (www.ismorethan.com)
