We’re definitely curious as to what Nokia will be bringing to the table come MWC 2013, but until then we guess we will just have to be patient and hope that leaks and hints clue us in on what to expect. In any case the folks at My Nokia Blog have spotted a mysterious looking Nokia device in an advertisement meant to showcase the Lumia 920 on Dutch carrier, KPN. Based on what we saw in the video (embedded above and around the 0:05 mark), this particular device features curved edges which is definitely not of the Lumia 920’s design. Instead it appears to be something of a combination between the Lumia 822 and the Lumia 620, suggesting that perhaps this mystery device could be another budget Windows Phone offering by the Finnish company. Either way with the Lumia 920 currently being Nokia’s flagship smartphone, we doubt that they will be introducing a new flagship device so soon, but we guess we will just have to wait and see. We will be at MWC 2013 so be sure to check back with us then for all the live coverage of the latest news!
