Recent Microsoft Surface Pro 4 gossip suggests the upcoming device may be formally introduced at a special event in October. The device is expected to run on Windows 10 upon launch. Meanwhile, the Surface Mini has failed to materialize this summer despite rumors to the contrary. The release date for the Surface Mini remains a mystery.

Of important reminder, the name Surface Pro 4 is an informal name used by tech observers to refer to the rumored device. Hence, the Surface Pro 4 may go by a different name when Microsoft decides to launch the successor to the popular Surface Pro 3.

Will Microsoft Unveil the Surface Pro 4 in October?

According to The Verge, the Surface Pro 4 may be at the center of a special launch event in October.

The publication allegedly had sources confirming that two new Lumia handsets, the Surface Pro 4 and the Band 2 will be unveiled at the upcoming event.

However, Microsoft has not confirmed whether such a gathering is taking place. Still, the software giant is planning to give a demonstration on Windows 10-related products at IFA 2015. The annual conference will be held on September 4 thru 9 in Berlin, Germany.

Surface Mini No Show This Summer, Microsoft Dismissed Rumors

In July, a rumor started by @evleaks claimed that the Microsoft Surface Mini is coming this summer. Since then, a number of observers have called this speculation into question.

At roughly the same time as when the rumor came out, ZDnet reported that their sources could not confirm the existence of the Surface Mini. Apparently, Microsoft had run into snag while working on the touch-first version of Office Suite. The technology was reportedly intended to differentiate Mini from other devices. As rumors suggest, the Surface Mini was deep-sixed at the last minute because not all the touch-first apps were ready for general release.

Now into September, there is no word from Microsoft regarding a potential release for the Surface Mini, which is said to be the smaller version of the Surface Pro series. The closest to a response by the tech titan came from Microsoft's Corporate Communications chief Frank Shaw.

"Was there a 'crazy rumor day declaration that I missed?" Shaw had tweeted.

For now, a 2015 release date for the Surface Mini is not very likely at this time - especially because signs are pointing to an impending Surface Pro 4 release.
