This isn't exactly "new", it's been like this for a week or more but when you search for popular brands in Google's search results, if they have Google+ Brand pages - the search results for that brand will add the Google+ information.
The added details include:
- Link to the Google+ Brand page
- Most recent Google+ post
- Most recent Google+ photo
A WebmasterWorld thread is waiting for Google Product Search and +Brand pages to be combined where searches for products return not just product images but Google+ data from the merchant/brand.
Forum discussion at WebmasterWorld.
