It’s been rumored and now confirmed: Nokia will be in San Francisco the same day Microsoft launches their Build 2014 developer conference. Coincidence? Of course not. Microsoft is expected to announce Windows Phone 8.1 in the early morning keynote, with Nokia taking their stage later in the day at 5 PM at their own event.

The last time Microsoft announced a major OS update – Windows Phone 8 – there was a delay of a few weeks before Nokia was ready to launch the Lumia 820 and Lumia 920. This time, that gap has closed.

So what to expect? We have a hunch there will be at least two devices:

  • Lumia 630 aka ‘Moneypenny’
  • Lumia 930 aka ‘Martini’

The Lumia 630 is expected to have the following features:

  • 4.5 inches touch screen
  • 854x480 resolution
  • Virtual touch keys
  • Size: 129.5 x 66.7mm.
  • Qualcomm Snapdragon 400 processor
  • 1GB RAM
  • Dual SIM (variant)

In terms of the Lumia 930, surprisingly not much is known at this time. We’ve heard from our own sources that it’s an “international Lumia Icon”. That makes sense in terms of specs, as the Lumia Icon would make a great successor to the venerable Lumia 920. However, we bet it looks more like the traditional Lumia ‘fabula’ design, meaning it will be less conservative than Verizon’s design choice. So you know, probably some actual colors and rounded corners.

Then there’s the mystery device: ‘Goldfinger’.

Not much is known about this phone except that it has no buttons and it uses a new sensor system for gestures. Some real cutting edge stuff. In terms of specs and design though, it’s a black box. We’re not even sure it’s ready to be revealed, which is why it’s going into our ‘maybe’ category for now. [Update: We've now heard that this phone and gesture system is not expected until next year. Sorry folks!]

Regardless, Windows Phone Central will be there en masse next week, with myself, Sam Sabri and Mark Guim all bringing you the best coverage. Stay tuned.
