According to a recent leak, trying to predict an upcoming Nokia product, the tablet which we’ve known so far under the codename Sirius, will apparently be called the Nokia Lumia 2520.
Depending on which reports you tend to believe, the Lumia 2520 will land on October 22, together with the Lumia 1520 phablet, or at another date. Nokia has already published some teasers for that day. As far as the specs for the Sirius, now Lumia 2520, are concerned, the slate is expected to run Windows RT and pack a 10.1-inch 1080p screen with a quad-core processor.
