But as you said, it's also not the worst idea to hold off on any changes right now, until we see how this all shakes out,
Someone earlier said they were worried. That made me think just wait a while there'll soon be something new to worry about. For webmasters Google is a bit like what they say about the weather in Scotland. If you don't like the weather just wait a while there'll be something different along shortly.
Having said that there are things that can be done that should not harm even if things do change. Personally I'm definitely doing an audit of my internal linking structure and I'm seriously considering some form of additional navigation links on very page to focus additional anchor text onto key pages. I'm certain that this is the right move in my niche and I can't see how it will do harm if there is a change.
