We've seen Google testing big sitelinks many times so far. It seems official now (or rolling out gradually). It's so huge that it occupies above the fold.
Sitelinks will now be full-size links with a URL and one line of snippet text—similar to regular results—making it even easier to find the section of the site you want. We’re also increasing the maximum number of sitelinks per query from eight to 12.
