Google Insights for Search: What next?

In addition to Google Trends, Google are now offering Google Insights for Search (http://google.com/insights/search/#)(via TechCrunch). Not only can you filter the terms by category, for example helping to distinguish between Apple (Computers & Electronics) and apple (Food & Drink), but it will also give a nice visual representation of the geographic data.

We can now quickly see that the Iran is the country most interested in webometrics:

The maps also offer a whole new type of vanity searching. The "David Stuart" brand has yet to make major inroads in Africa, Asia or South America. I was grateful, however, to find that my own vanity searches had not overly effected the results (at a city level London is the hub rather than Wolverhampton).

Some bloke called Barack Obama, on the other hand, seems to have made inroads all over, with the exception of the Middle East.

The obvious question, based on the directory structure of the Insights for Search URL (http://google.com/insights/search/#), is what other insight services are Google going to offer? Insights for Maps? Insights for Shopping? Insights for News?
