Google made a pretty interesting announcement today that could have bigger consequences than it first seems. The basic news is that Google announced it will be branching off of WebKit to support its own browser rendering engine, called Blink. This should make Chromium development much easier overall, but it could end up causing trouble for iOS.
The reasoning behind the move according to Google is that it is too much work to deal with WebKit, which has a ton of code that is used to support WebKit 2, which is used by Apple for Safari, but isn't used by Chrome. The move will allow Google to move faster with Chrome development by making it less complex. Opera, which recently announced it was switching its browser engine to WebKit, has said that it will follow Google's branch and support Blink.
