I'm starting to doubt Nokia will show anything in MWC or at least have have units for people to test. I doubted if we will N9 in MWC, but now i'm starting to doubt will we even see Symbian devices.
Nokia got it's "stands" in hall 4 and hall 4 is actually for meeting rooms. Exhibiton areas are hall 1,2,7 and 8.
Nokia's space is just 3 tiny rooms over at hall 4. http://mwcfloorplans.eventex.co.uk/hall-4

And i don't see Nokia announcing anything in Elops keynote as it's in the last day and they have already been given a topic to talk and they share it with 3 other keynote speakers.
Honestly even Capital Markets Day next month seem more promising place for Nokia to make any kind of announcements imo.
