Just like with ANY supposed Apple leaks based on patent submissions, take these with a grain of salt.
A company as large as Apple patents everything pre-emptively, but it’s no indication of what they will or won’t bring to market.
If you read the article, the patent was first applied for in 2010, a year before X even came to market. And while you can’t infer ANYTHING from patent drawings, the iconography is certainly more 7 than X oriented.
