The invitations sent out by Nokia include the slogan "meet us under the tree". While it might be fun to speculate about what Nokia and Microsoft might be doing under the tree, the reality is that Nokia has traditionally favoured environmentally friendly stands (and phones). Even so, some green-themed announcements, under the cover of a peaceful birch tree, remain a distinct possibility.
Nokia is expected to announce a number of Lumia Windows Phone devices. Leading the rumour mill is the Lumia 630 / 635, a mid tier device, with on-screen command buttons in place of the more usual physical (capacitive) commands keys. The Lumia 630 is speculated to be a dual-SIM device with 3G connectivity, while the Lumia 635 is said to be a single-SIM deice with 4G (LTE) connectivity.
An updated version of the Lumia 920 may also be on the cards, with an educated guess suggesting a device with a 5 inch screen, 20MP camera, and Snapdragon 800 SoC (i.e. a smaller version of the Lumia 1520). Such a device, which might be referred to as the Lumia 930, would be the global version of the recently reveled US Verizon specific Lumia Icon handset.
Nokia is also expected to announce some Bluetooth Smart themed accessories, following on from the universal availability of Bluetooth LE in Lumia Windows Phone 8 devices, a result of the Lumia Black software update.
MWC would also be the logical launch venue for the Nokia Normandy, an Asha device running on top of a forked version of Android (i.e. Asha OS and Fastlane UI on Android, rather than Series 40).
