My concern is that the ability for Google Analytics to parse information on specific keyword queries will be diminished. The article hints that Google Webmaster Tools will be exempt from the problem, and I've never relied on Webmaster tools as a go-to for tying specific keyword queries to Goal Tracking (form submissions and sales).
The community's thoughts on this one are appreciated.
