"iPad mini" is currently showing up as a suggested search result in Apple's online store. But so is "iPad air". And "iPad nano". And "iPad little". And more.
Search results from Apple.com have previously identified accurate product names, including the iPhone 5, but past behavior isn't always an indicator of future behavior. Maybe it's just an anomaly in Apple's database. Or maybe, just like iOS firmware strings have been found for iPhone 10,1, maybe someone on Apple's team is having a little fun this weekend.
